[FIX, #645] fix memory access violation in ms-numpress
[FIX] MS Numpress upstream fixes

- update to commit 21259b4a9eba62e8c398c2cfef4e80b875ff91d5 at
  https://github.com/ms-numpress/ms-numpress
[TEST] add test for corrupt numpress mzML file

- the corrupt file should not be read but rather a ConversionError
  should be thrown
[FIX] numpress fix

- wrong description was used for MS:1002313 CV term
[FIX] add CV terms for MS Numpress

- allows OpenMS to also read ms-numpress files (and not complain any
  more about unknown CV values)
[FIX] added .gitattributes to test data folders

 * disables line ending conversion for test data
 * fixes #647
[DOC] add OpenSWATH classes to DefaultParamHandlerDocumenter
[FIX-#618] fix spelling errors across OpenMS header files
[FIX,BUILD] fix pyOpenMS build without contrib

fix pyOpenMS build on certain Linux distributions when no contrib is
present (libsvm is not found due it being in a subfolder of
/usr/include).
[FIX] fixes MSVC compile issues in StatisticFunctions_test

[FIX, TEST]

fixes #653
[FIX, INTERNAL]

on Windows the tests below might fail when OpenMS is configured with a
OPENMS_GET_TEST_DATA_PATH which contains a small device letter, e.g.

//#define OPENMS_GET_TEST_DATA_PATH(filename) (std::string("c:/dev/oms/source/TEST/data/") + filename).c_str()

since getLoadedFilePath() used to call Qt to create absolute paths and
this changes "c" to "C", making the string comparison like

TEST_EQUAL(di2.getLoadedFilePath(), OPENMS_GET_TEST_DATA_PATH("File_test_empty.txt"))

fail. The fix here is to modify/fix the path only if its not absolute,
thus for our tests it will stay untouched since OPENMS_GET_TEST_DATA_PATH
is always absolute.

Alternatively, one could modify each(!) test (e.g. convert to lower case
before comparing),
but this creates invalid paths on unix and is error prone (since the next
developer will surely forget to use it).

Failing tests are

123 - ConsensusXMLFile_test (Failed)
126 - DTA2DFile_test (Failed)
130 - FeatureXMLFile_test (Failed)
142 - MS2File_test (Failed)
143 - MSPFile_test (Failed)
149 - MzDataFile_test (Failed)
153 - MzMLFile_test (Failed)
158 - MzXMLFile_test (Failed)
