Improve tab order in wikis
On Redmine 0.8.4.devel.2819 (MySQL), and on the current rev as hosted on the online demo, the tab order is either undefined or ill-defined (I haven't looked) for some of the pages. Specifically, it would help a great deal if after clicking 'edit' on a wiki page, the focus was set to the main text field, if not directly, than at least after a few clicks of the tab key. Currently, it's about 36 clicks. This is clearly for those who are heavy keyboard users. I'm one and thought it would be nice. If I could code ruby, I would.
