DDMsgReader: Text search now ignores user scan configuration

See merge request !189

DDMsgReader: When doing a text search, it now ignores the user scan configuration for sub-boards, to ensure it will show any results of the text search.

attr_conv.js: Replaced Sync attr literals with hexadecimal version so that "use strict" can be used

See merge request !188

Solves problem of status output lines being interleved with console
output (e.g. from print()) after executing a script.

When using the "Access to Sub-directories" option for a library, the auto-created directories did not have their virtual sub-directory name set. Pretty sure this was introduced along with the http access to filebases after v3.19b.

Also, only de-dupe the sub-directory names based on the directory name and not the code/code-suffix for now. Next up: auto-gen unique internal code when needed.

By default, each file transfer directory's internal code suffix is
used as the source of the sub-directory of the virtual path used
to represent a file area in the FTP and Web servers. Now, a sysop
can change that source to either each directory's short name or
long name, if they prefer.

For MRO, because he asked (on DOVE-Net).

DDMsgReader refactor for sysop save to BBS machine & attachments.

See merge request !187

DDMsgReader Version 1.49 - Refactor: Simplified saving a message to BBS machine for sysop (as-is, less processing); removed attachment stuff for pre-Synchronet 3.17; moved hasSyncAttrCodes() to attr_conv.js because that's where it needs to be.

DDMsgReader: Improved display of ANSI messages via the use of the Graphic object

DD File Area Chooser: The false command-line parameter works again

allowing the user to choose the file directory within their file library.

DD message area chooser: Updated to try to prevent an "undefined" error when only choosing a sub-board within the user's current message group

See merge request !184

This exposes the Synchronet internal sbbs_t::progress() method used to
display a progress indication bar, e.g. "[ Scanning 10.0% ]" with the bar
backfill effect (when supported by the terminal).

This can be used to force a close of the user.dat file, if open. Rather than
waiting for an out of scope User to get garbage-collected, this method could
be used to force a close of the user.dat file, if it's open.

This is normally the first count value and even if we *just* output a progress() for a previous operation, we still want the first progress() call for the operation to display.

DD Upload Processor: Removed the chmod updates because they're actually not needed.

See merge request !183

DD message area chooser: Updated to try to prevent the error "this.subBoardListPrintfInfo[pGrpIdx] is undefined" when only choosing a sub-board within the user's current message group.

Some antivirus scanners (such as ClamAV) need a command line parameter to pass the file permissions descriptor to the scanner.

DD message area chooser: Updated to try to prevent the error "this.subBoardListPrintfInfo[pGrpIdx] is undefined"

DD message area chooser: Updated to try to prevent the error "this.subBoardListPrintfInfo[pGrpIdx] is undefined"

e.g. directive argument in the range [-255, 2147483645]

Suppresses GCC warning. I suppose some of these fields could be more digits
than expected.

This appears to fix the "lots of user.dat files open concurrently" behavior
that remains when a browser/client has the webv4 page open for a long
duration.

Eventually, the User objects created in this loop would be cleaned (and the
user.dat file descriptors closed), but the default garbage collection interval
(configurable) is 1000 calls to the CommonOperationCallback function. This could
be as as long as 1000 times through this loop before GC occurs.

Since this is not a performance sensitive loop (we have a call to sleep for a
full second) just force a garbage collection for each loop iteration.

SlyEdit: Removed high-ascii characters from the JS files to avoid issues with editors changing encodings

See merge request !180

SlyEdit Version 1.78: Removed high-ascii characters from the SlyEdit JS files; used ascii() with their numeric ASCII values instead. This should avoid issues with text editors converting characters incorrectly.
