[FEATURE REQUEST] Logging with Timber

[abelgardep]

Contribution by @hannesa2

It's about to change logging from self-made to Timber.

It removes the logic to display log and simply uses a Fragment from logging-lib.

It keeps all previous functions like

• searching

and adds

• a tab for ownCloud Filelogging view
• a tab for Logcat view
  • to see what happens on other processes too
  • to log what ownCloud forgot to log
  • within release build type !
• share log
• adds filter for Verbose, Debug, Info, Warning, Error

Eg, when you select Info you will see only Info, Warning, Error entries and filters out Verbose, Debug

So it helps to investigate, what's wrong with ownCloud.

All is encapsulated with a logging lib which I use in several places.
I kept to old Log_OC , to easy migrate and do not touch all files. Especially when you do a huge refactoring

One major advantage for developers:
Before:

NEW: you can click log log line and jump direct to code ! You see the linenumber as well
