Gradle cleanup

Update gradlew and android gradle plugin
Only run assembleDebug by default(faster builds)
Run gradle as a daemon(faster builds)
Move configuration to a dist file, add gradle.properties to gitignore
Remove crash reporter

No longer useful
Lots of changes

Yay, the project is still alive!
A list of some of the changes(non-exhaustive):

* Dev build has a custom version banner now
* Don't change window title to match buffer(causes crashes and isn't
  valuable)
* Big changes with how connections work(more abstract)
* Soft keyboard now has send button instead of enter
* Chat input box is now has better spellchecking/corrections
* Service now actually runs in the background(and survives android
  trying to kill it)
* Fix various crashes
* Introduce other crashes(most likely)
hide close and nicks from menu when not in buffer.

set a max length of 13 on prefix so long nicks don't take over.

(cherry picked from commit f478d9a01771cdefcccd26efd3375b49e82cc588)
Allow chat input to grow up to 4 lines tall

Makes it way easier to compose slightly longer messages, though we can
no longer have enter to send(depending on the user's chosen keyboard).

We'll see if this is a good tradeoff or not.
home button navigates to buffer list
