Need to limit custom prof text to 15 char about dwarftherapist HOT 6 OPEN

This isn't a bug. The game allows arbitrarily long profession names and 
nicknames.

This is actually a bug. Kind of a nasty one at that. If custom professions 
longer than 
15 characters are entered, it's actually overrunning a std::string buffer in 
the game. 
This can cause corruption but doesn't 99% of the time.

Will have to do something about this...

To fully match up with what VC++ does with strings, you need to track the 
original
string length on read.  If the original string is empty or < 16 bytes, you can 
safely
write back anything up to 16 bytes.  If the original string is 16+ bytes, you 
can
safely write back up to that length (since it goes into a buffer allocated 
separately
from the std::string structure.)  That is, I could customize the profession 
through
df to 24 'A's and then replace that with a 24-character string through DT, and 
it
should be able to write that back with no corruption.

And, of course, none of this works on Linux :(

A visual solution would be to have the data entry box:
* Presented in a mono-spaced font
* Surrounded by a bitmap that is one color on the left and another color just 
past
valid input.

This would mark the end of text length for easy editing, but not impose a hard 
limit.
