[issue/186] Add the shortcut information to the tooltip

The information about what's the shortcut key for a command is completely hidden from the UI. This will make it so that that shortcut key shows in the tooltip when hovering a button and also in the button's text.

Add Indent and Outdent commands for WYSIWYG

Some say that SCE sukz because you can't nest lists while in WYSWIYG. Well, now you can.

Tested with the BBCode plugin and it works (does not work when not in WYSIWYG)

Indent only for lists for now

After a lot of searching, it's better not to have an indent, at least, until we have some nice amount of study.
Until then, let's just have the indent to allow nesting of lists.
I've made an extensive list of tests to make sure this would cover all the situations with IE10, Firefox 23 and chrome 28. I think I have all covered.
Fixed spaces problem
Small improvement to ol, better numbering

Changed numbering to ol so that it follows the:
1
1.1
1.1.1
1.2
1.2.1
1.3
1.4
2
2.1
etc...
style of numbering.
Specially noticed when using nested lists.
