adding a slew of updates for markItUp, reflecting release of markitup 1.1 and many updates (made out of cvs due to having pre-release copy of markitup plugin). future updates are planned to be managed via the markitup issue queue on d.o

add CSS rule to prevent background images on markItUp buttons. Garland and potentially other non-core themes set background images on li's.

#243383 - turning the teaser splitter off for pages using markItUp, so we can avoid teaser issues with pages where the splitter hasn't been previously triggered.

#243494 - resolving Garland CSS conflict regarding .preview class, and overriding standards markItUp skin textarea width (700px) for more Drupalish behavior (99% width).

#243383 - target only visible textareas when invoking the plugin. Allows us to leave Drupal's teaser handling alone. Also removing Drupal's grippie, since markitup provides its own.

Initial commit of markitup module. The markitup module integrates the jQuery markItUp! content editor plugin for use in Drupal 6.
