Right now modules are loaded from :

• global path
• /bin/ if running with -debug

For mono I modded scriptcs to always look in /bin/ for convenience.
How about we allow the module lookup path to be customizable?

For example:
scriptcs file.csx -modules mono -modulepath /home/filip/module
scriptcs file.csx -modules FancyConsole -modulepath bin

or simply set the modulepath in the scriptcs.opts
