This "basically works" but needs a *a lot* of work and has a bunch of
issues to resolve.

Guidance Needed:

• There is a bunch of copy and paste code which is not the greatest. Inheriting from PhabricatorProjectBoardController seemed neither good nor how idiomatic (it's final after all). There may still be some un-needed cargo cult code.
• Getting some of the outstanding problems fixed will probably involve changes to ManiphestTaskResultListView which I didn't want to do unless this was on the right track. Re-using ManiphestTaskResultListView seems like the right thing to do but it's a bit wonky.
• I think I mostly got the style right, or at least arc lint seems happy, but emacs has been disinclined to indent like this so I could have done something icky.

Current issues:

• changing order in column view does not really change natural sort order, probably best do dissallow but need the tasks to be 'selectable' for ManiphestTaskResultListView.
• filters from the board are not retained when clicking on individual columns.
• batch edit takes you to a maniphest page, which may or may not be good
• advanced filter causes cards to be grouped by priority
• dummp text needed to keep menu buttons from being cut off
• something inconsistent problems with selecting individual gripable tickets. Select all works but selecting individual ones does not. I'm having the same issue on other vanilla phabricator installs such as this one so I'm confused.
