Compromise on wording for https://github.com/fontforge/fontforge/issues/289

To get file version numbers up above would require a much larger re-write,
but this mod is much smaller since it only affects one printf statement.
rename config.h to fontforge-config.h; clean configure-fontforge.h
include fontforge-config.h in fontforge.h, for those linking fontforge
clean code with GCC warning
less jitter during undo/redo process when talking to the server.
Detection of slow network (no response from server to update sent)
and dialog allowing reconnect.

Windows now show if you are in a collab session or not and if you
are the server or client, or are in a session that was forced to
be disconnected.

Merge pull request #377 from JoesCat/master

minor update to stamper.c (when building stamp.c)
clean GCC warnings
cleaning round 2
clean const stuffs; fix startui.c
use MODTIME_RAW
don't remove config.h_vms
A bit of code cleanup, more comments here and there.

Major change, collabclient.c is now always built, but the body
of the functions are #ifdef guarded. This way code through the rest
of fontforge can call the collabclient_foo() functions without needing
any #ifdef guards. They simply do nothing when the zeromq + collab code
is not built.
