F-Droid and FOSS

[czlucius]

Refactoring of codebase to be compatible to F-Droid, to have a build flavor that does not have proprietary libraries. See #2, #5.

Challenges

• [ ] Detecting of data types(e.g. URL, E-mail) -> may create a library for that ZXing does not detect type of data, and returns it as a raw string. Code needs to be written to parse this data.
• [ ] Type Integers
• [ ] Generic classes so that general and foss can extend
• [ ] Others

Code will be pushed to the foss branch soon
