More accessible build process

[mjsir911]

This patch attempts to modify the build process to be easier to run and maintain. Heavily inspired by notes in issue #160

The app compiles and installs, but the localization is stuck in chinese and libpython2.7.so is not found, so I cannot test it 100%

Build tested under gradle 4.10.1 and gradle-5.2.1

Overview of changes

• Bumped failing versions of various dependencies
• Stopped failing on error on linting
• Removed depracated options
• Modified build process to not rely on developer's hardcoded paths (local.properties)

If you can point me to how to get localization up and running or libpython, I can test further
