* Pre: Bump version to 0.3.2.
This just needs to be greater than 0.3.1, the last version I pushed in
testing.
* Publish logins AAR to nalexander's personal bintray.
* Post: Bump task timeout for build and publishing.
Building everything for three architectures just takes a long time --
15 minutes per architecture or more.
I investigated speeding this up, and I conclude that compiling the
architectures in parallel is both work (you need to work around cargo
a little bit, and you need to use a Make jobserver to limit the total
thread pool) and doesn't pay off (I witnessed only about a 5-10%
speed-up locally). My guess is that it pays off even less in AWS,
where IO throughput is relatively low and context switching relatively
more expensive.
