Make labels more human-friendly

[jdm]

They're currently designed for power users and ordering concerns. We can do translations like this:

• A-foo => "area: foo"
• E-easy => "good first PR" (maybe even put a friendly star next to the issue)
• E-less-easy => "mentored"
• L-foo => "language: foo"
• B-foo-bar => "foo bar"
• S-foo-bar => "status: foo bar"
• I-foo => "category: foo" (not thrilled with this one; we may want to just ignore I- labels)
• C-foo-bar => "status: foo bar" (whee organizational duplication)
• P-foo => "platform: foo"

+1 in general. Some specific suggestions:

• we should cull many of the labels in general instead of keeping them and renaming
• make the labels have no spaces after :. like area:foo.
• the only useful B- label in my opinion is B-meta, but agreed it should just be meta. remove the rest.
• For L- I suggest lang:foo
• There seem to be two classes of C- labels. The first is closed reasons, which I think should be closed:$reason. The second is status of which the only really useful one is assigned. Maybe delete the rest and make C-assigned part of status status:assigned.
• For I-, I'd cull a lot of these, and just do type:$type and keep mainly things like type:crash, type:leak etc.
