BUG 1070001: Re-Org Stylus - wikiedit

Renamed classes to make them more modular:
- documents -> document-list
- deleted move-decendatnts-list and changed elements to use document-list
- move-lookup-link -> parent-suggest-link
- contributor-sub -> contributors->sub
- choice-list -> revision-list-head
- revision-list -> revision-list-contain
- compare -> revision-list-controls
- various changes to more granualr class names inside revision-list
- action -> title-prefix
- kumascript-errors -> kserrors
- kumascript-details -> kserrors-details
- kumascript-detail-toggle -> kserrors-details-toggle

Move Page:
- changed title to match style of create/edit/translate pages
- removed move-decendatnts-list and changed occurances to document-list
- removed class "editing" because it was not having any styles applied to it (this allowed me to decrease specificity of the declaraion)

Everything else was done to decrease specificity and redundancy, or move declarations into their own files for maintainability.

Wasn't sure what to do with the broadly defined elements declared at the beginning of wiki-edit.
