Bump Application Version to 1.3.1

Updated versionCode and versionName for release of 1.3.1.
Fix search results were returning not using the right url.

This was the cause of not returning the right anime/manga details.
Bump Application Version to 1.3.2
Fix Search Crash

Searches were crashing because we weren't properly returning an empty
JSON Array. Made it so an actually blank array is returned. Also, added
a check for the error message given by the new API in response to an
empty search result list.
Repair Bad Check for Search Error

It turns out some words contain "error" in them, like terror. That last
commit broke those searches. We should be properly checking for a 404
return code, not a string in the response.

Gradle update and optimisation

Updated Gradle to 1.12 and the Android gradle plugin to 0.10. Now
Atarashii can be built again without troubles (with the latest Android
Studio 0.5.8). Also done some optimisations to the gradle config:
- defined things required for all modules in the root build.gradle
- kept the wrapper tasks in the build.gradle files for easier update
  in the future
