FLUID: adds greatly enhanced Shell Commands (#774)

The user can add an arbitrary number of highly configurable 
shell commands through the setting panel. The commands can
be saved as user preferences, inside the .fl file, or exported
to an external file. Shell scripts can be limited to individual 
platforms, can have shortcut keys, etc. .

* documentation will follow
* support to call `fltk-config` will follow
