Up to [Public] / Amaya / amaya

Many registry, configuration files changes:

Initialized the TMPDIR registry entry so that it points to "c:\temp"
under windows and "/tmp" under Unix. Under Windows, if the directory doesn't
exist, it'll create it.

Added a new registry entry, APP_HOME. It points to the directory where
a thot application may store its temp files. Under Unix, it's
equivalent to $HOME/app-name. Under Windows, it's TMPDIR\app-name.

Renamed the default configuration files as win-thot.rc and unix-thot.rc.

The .thotrc file is now stored as APP_HOME/thot.rc. There's no automatic copy
of your old .thotrc file. You'll have to move it and rename it yourself.

Don't forget to recompile your compiles (prs, str, ...) after you make
the update. Otherwise, they'll try to access the (now-deleted) thot.ini,
thot.rc files.
