In progress: Generate fixed list of config

- Generate a list of configuration for the tests/ project
  - Will be used to compile specific file for time benchmark
- Put comment on how add a compiler plugin in SBT
Working redefinition of config per file

- One configuration per file to compile. Unfortunately, it is way
too slow to load all SBT definitions.
- Let's try to figure out something different.
Removal of uneeded .java files from scalalib

No need of those test for our benchmarking.
Benchmark for time works

- More precise benchmark for time, based on scalac only (no SBT)
- Some files cannot be compile due to dependencies (will have to be checked)
- Scalac version 2.11 only

TODO: plot all that.
