Commit number 42 wohoo!

Refreshed the styling for the wordwall module. Now includes a selected item indicator. And the colour has been toned down and improved somewhat.

Fixed bug found by dman: Data loss when re submitting a form has been fixed. Default values and wordwall form freeze effect now happening.

Completed documenting the hook definitions.

TODO still: remove variables on uninstall.
