This is the first step (the hardest part):
* repo file list last commit message lazy load
* admin server status monitor
* watch/unwatch (normal page, watchers page)
* star/unstar (normal page, watchers page)
* project view, delete column
* workflow dispatch, switch the branch
* commit page: load branches and tags referencing this commit
The legacy "data-redirect" attribute is removed, it only makes the page
reload (sometimes using an incorrect link).
Also did cleanup for some devtest pages.
