txt2key() - parsing key binding specifications

Browse Source 
While testing some addtional ?i (list of key assignments)
changes, I wanted to give every key a binding.  When I tried
BIND=M-^A:exploremode
the text to key conversion didn't like that.  This adds support
for M-^x and M-C-x plus variations where dashes are omitted.

This adds support for ^? even though that isn't really a
control character.  I bound #terrain to it and surprising--to
me at least--the <delete> key worked to invoke that command.

Also changes 'char txt2key(...)' to be 'uchar txt2key(...)'.
