(return value) since v3.15.

If a filename had no extension, it could not be added via batch download
list since this code was truncating all white-space off each line read.
Now it will just truncate end-of-line characters.

New Features:
- Multiple bindings for each service
  Use comma-separated interfaces on Interface= lines in the ini file.
  Default is now "0.0.0.0,::"
- IPv6 support
- TLS support for the webserver and (non-static) services
  New TLS option in services.ini (ie: Options=TLS)
- Decrease LEN_SCAN_CMD to 35 chars, increase the CID field to 45 chars,
  and rename the MAIL_CMD string to IPADDR.  I think this frees up the
  note field for SysOp use.

MinFileSize and MaxFileSize keys in the [ftp] section of the ctrl/sbbs.ini file
these values default to 0 which effectively applies no min/max to uploaded
files. Set MinFileSize to 11 to defeat the recent penetration testing seen
uploading 10 byte files with random filenames (8 alpha cars ending in ".txt")
with 8 alpha chars in the file, followed by a CRLF pair for a total size of 10
bytes.
Fixed bug whereby failed/aborted uploaded files would be left (not deleted).
Log errors when any file deletion fails in the FTP server.

code for the size/credit value.

downlaod), and the "check for file existence" option is enabled, then get the
file size as well and display that instead of the credit value. This fixes the
problem with files whose size has changed after they were uploaded or added
to the filebase. Directories which are not free still displayed with each
file's credit value (since that may not have any correlation with the file
size).
Display file sizes and credit values in a shorter more easy to read format
with suffixes for gigabytes (G), megabytes (M), kilobytes (K), and bytes (B).
Using an uppercase 'K' now to be more consistent with modern conventions
for abbreviating Kilobytes/Kibibyte (1024 bytes).

Allow global services.ini keys to edited on the "General" tab.
Moved "Sound" tab to the far right.
Still need a method for deleting keys.

Added Help->Donate menu item.
