[FEATURE] change file format of cached files

- write spectra and chromatogram number at the end of the file
- allows to start writing spectra without knowledge of the number of
  data to write
- [DOC] fix output
[DOC] clearer documentation
[API] simplify API of MSDataCachedConsumer

- it is now longer necessary to know the number of spectra and
  chromatograms beforehand
[FIX] ~40x speedup for constructions of unmodified AASequence
some benchmarking
[BUILD] change working boost version numbers

- since boost 1.46 does not work any more and 1.48 works, we should not
  have cmake detect a working version of boost and use that
[BUILD,FIX] bugfix: add all Wm libraries

- before, only the last wildmagic library of the WM5_LIBS libraries was
  added to _WM5_LIBRARIES
- fixed this, now multiple Wm5 libraries are possible
[BUILD] enable finding wildmagic on debian

on debian, libwildmagic headers can be found under
/usr/include/libwildmagic/ and also searching this path, system
wildmagic can be found and used with OpenMS
[BUILD] add default path for searching libraries

- on debian systems, most libraries are in /usr/lib and /usr/include so
  adding this as default would allow for very simple cmake commands
[TEST] remove test for non-Windows platforms

- using the debian system libraries, this test also fails and it is not
  clear why we should have tests that only work under certain
  circumstances and certain platforms
