Screen refresh optimization: Only do PageUp and PageDown if not already at the top or bottom of the menu items.  If already there, don't redraw the menu items.

Change wordage of recvline() returned null exception (it's a timeout).

- reverse_mail (default: true), show the newest received at the top of the list
- reverse_msgs (default: true), show the newest at the top
- track_last_read_mail (default: false)

Store and retrieve user properties per-sub or mail-type (your, sent, all).
This will enable per-user per-area preferences. Right now, just the last read
mail msg number is stored here.

The new property nextDrawOnlyItems is an array that contains indexes for specific items to be written the next time the menu is drawn.  It can be used as a display optimization; for example, if the menu is redrawn in an input loop in the calling code and the selected item changed on the same 'page' on the menu, then the calling code can add the indexes of the 2 items to redraw the next the the menu is drawn so that the menu will only refresh those 2 items on the screen rather than the whole page of items.

Library names (case-sensitive) for which you would like to have their
directories automatically added to your tickit area list.
Directories whose names are invalid area tags (e.g. contain a space) are
not included.

For example, this is a valid single response:
220-I'm so clever
221 Yes, yes I am
220 So very clever

 Error 24 opening '../fido/outbound/5e7a2520.pkt'.  Not sending.
instead of this:
 Unable to open '../fido/outbound/5e7ab832.pkt'.  Not sending.

Error 24 is "too many open files", btw. Another problem to solve.

1) Fix ACCT command
2) RMD response is 250, not 221
3) When sending a file, throw an exception if a 226 response is not received
4) Before sending a command, if there is data available on the socket,
   log an error (don't throw an exception).

The alternative is JSON, really, but I like .ini for this type of list.

This needs testing and validation feedback, ASAP, as it's mere existence in
the exec directory means that it'll usurp qnet-ftp.bin (!) and if it doesn't
work, our precious QWKnets will suffer. :-/

... Another (rather large) nail in Baja's coffin.

Use this throughout lbshell.

The F and L keys now nagivate to the first & last pages, respectfully (unless the calling code has added either of those keys as additional keys to exit the input loop in case the calling code wants to handle those keys for something).  Also, fixed a minor bug in calculating the length of items to print when the scrollbar is enabled but not refreshed on the screen when writing the items.

Requires the latest SCFG with the new "-misc=<val>" option.

For a screen update optimization, implemented a way to temporarily restrict which part of the items to draw the next time Draw() is called (and thus when WriteItem() is called for each tiem).  There is a new property in the DDLightbarMenu class, nextDrawOnlyItemSubstr, that can be set to an object with 'start' and 'end' properties specifyign the start and end indexes (1 past the last char index) of the item strings to write in the menu the next time Draw() is called.  Draw() will then set nextDrawOnlyItemSubstr to null when it's done.
