Add an unit test for compilation without warnings

Browse source 
An unit test which checks whether Nimble compiles without warnings is
added. Checking for three warning types cleaned in previous commits is
implemented:

 - [UnusedImport] cleaned in e8c7d5c

 - [Deprecated] cleaned in 3d6172e

 - [XDeclaredButNotUsed] cleaned in 7df2ef3

Other types of warnings easily can be added to the test by extending the
warnings list.
