Create help command generation.

[Omar A. Hachach]

The help command would list all the available modules and commands.
The command format is the following: .help [module] [page].

Doing .help would return:

Help Menu

Test Module - Test Module is a module made as a test.
Another Module - This is another module.

For more help, do .help [module] [page]
