Mikubot-2/plugins/gImages.lua
topkecleon 26c1299374 Rewrote help.lua and added markup support to several plugins.
help.lua has been rewritten to support "/help command".
New variable "command" has been added to plugins for the syntax (w/out slash) to be displayed in main
help message. "doc" will be displayed upon "/help command".

Output of >12 plugins has been reformated to utilize markup.
There is a fairly standard style throughout plugins.

get_word() in utilities.lua now has defaults for nil arguments.
