App update (Repositories merging)

[BobbyESP]

I've been making a lot of changes from two weeks to now. I leave here a list of the things that I've made:

• Home page UI fix (Home page shortcuts now are full clickable, now they're not adjusted to text)
• Lyrics well syncronized (also added no lyrics found)
• Moved the project to Kotlin DSL
• Fixed searching (now everything works fine)
• Moved hard-typed text to R.string declarations
• Splitted the builds in different ABIs (arm-v8a. armeabi-v7a, 86_64x, 86x)
• Deleted the option of Very High audio quality in non-premium accounts
• Added localization to the Spotify end-points
• Now the Listening History shows it all (no more unsupported Id's)
• Fixed that clicking the "More options" button in full screen player that stopped or played the track.
• Added Spanish translation
• Made a better README
• Added bug reporting and feature request templates to GitHub issues

(I think i wrote all haha)
