Crossfire 0.91.8 changes.

[Mark Wedel <master@rahul.net>]

 Since several people have asked, here they are:

Changes from Crossfire 0.91.7 to 0.91.8:

Messages about an objects speed no longer printed to the console.

When players exit maps, no longer inform all the other players.

install-same and install-font directives added to lib/Imakefile - used
if game is being installed to same font it was unpacked in.

Client now supports receiving bitmaps - server does not support
sending them, however.

Max experience achievable is based on max level, not a hard coded
value (although, at present time, max level is hardcoded to 100)

insert_ob_in_ob now returns an object - needed for client/server code.

check_inv function added to button.c.  Trigger will be altered depending if
the character has a matching item (or lack of a matching item.)

Option added to config.h to make it so that backup saves will save the player
back at home, instead of the present map.  Code adapated from code sent
by John Steven Moerk (jsm@axon.ksc.nasa.gov)

Minor bug in crossedit fixed that would cause it to exit if both
-p and -xpm is specified.  Both can now be specified - it will effectively
ignore the -pix portion.

New skills added, with corresponding code to use these skills (from Brian
Thomas) Use of skill code is selectable in the config.h file.

Two new spells: summon fog and steambolt (from Brian Thomas)

Enchant armor code added (from Brian Thomas)

Fixed bug in crossedit that would cause it to core dump whenever a non exit
was selected and then the enter command run.

Fixed bug in attack.c that was using info_all if CASTING_TIME was
selected.

Made it so that decrease_ob_nr will never decrease the object number below
0.  This fixes a bug in that remove_ob would calculate a negative weight,
and then call sub_weight with that negative value.  This ended up resulting
in weight being added to the player instead of subtracted.
