Fix an issue where headset focus would restart playback unexpectedly.
At some point during the broadcast refactor, I accidentally switched
the values of CONNECTED and DISCONNECTED when handling
AudioManager.ACTION_HEADSET_PLUG. This resulted in playback starting
for no reason in some situations.
Use body typography in more places, reworking the letter spacing as to
make it more pleasent to use with the inter typeface.
This should hopefully be the last time I fret over typography.
Everything should line up in the way desired by M3.
Update the contribution information and templates.
The contribution information and templates were growing a bit stale,
given that they haven't gotten a refresh since ~1.3.0. This commit
reworks them to be more thorough and straightfoward.
Add a CHANGELOG document that keeps track of the past and current
release notes.
Making all of our releases rely on GitHub to keep track of them is not
really a good idea, so this document serves as a record of past release
changelogs just as a pre-caution. It also allows a live preview of the
next version whenever something is changed.
