first attempt at implementing support for keys with modifiers
to use it, the keybinding have to be of the form mod:<modkey>:..:<modkey> <function> <keycode>
for instance in an ini file change findhh=h to findhh=mod:lshift h
As a special exception, FreeType can also be built with the 'makepp'
build tool, available from http://makepp.sourceforge.net.
Note, however. that you will need at least version 1.19 and pass the
option --norc-substitution to have it work correctly.
