v0.12.2rc2

0.12.1 got eaten by a goblin.

This is possibly a rough release, run at your own peril.

Changed

• Upgraded to lbry daemon 0.13, including updating API signatures
• Channels resolve much faster
• Internal refactor and simplification of lbry.js

Fixed

• Fix help menu force reloading whole app
• Possibly fixes file delete issue #182 (if not #182 is probably a bug in lbry)
• Possibly fixes startup issue #165
