Currently will display node activity (everything else non-functional)

* Bug-fix: bad drop file path if using startup-dir
  (e.g. "c:\sbbs\xtrn\game\/door.sys").
* Using SAFECOPY for buffer overrun protection.

Fix memory leaks in js_write() when using uuencoding and error conditions
occur.

NOTE: js_sendfile() should be using the xpdev socksendfile() function...
      The way it's currently working is just plain insanity.

Probobly not possible in a large number of circumstances simply due to the
possible very large size of the data involved... email attachments go
through b64decode for example, so it's probobly "Too Big" (unless I

This fixes linebuf leaks in both js_wordwrap() and js_quotemsg()

NOTE: js_readln() seems broken here... DigitalMan?

Fixes at least one memory leak in the spy function and at least two (three?)
leaks in unomitor.c

memory leak in the block copy function.

Fixes at least one memory leak (str was never free()d in ugetstr)

happening here with long uptimes.
