- removed obsolete output files in the analyses 'derivative' and 'interaction'
official support for Cygwin
- mostly an adapted merge of the branch 'cygwin'
- added Windows libraries for srcML
- expanded README and added INSTALL file with detailed information
- fixed some issues with the line separator in preparation scripts (only existing under cygwin)
- removed platform guards in 'analyses'
fixed a problem when detecting include guards and #ifdefs were deleted mistakenly, although they were no include guards actually
added installation information for xUbuntu 12.04
- removed threading from preparation.py and analysis.py (was too error-prone)
- fixed some minor issues when removing non-existing files
fixed a bug regarding TD_ifdef (erroneously removed tangling values)
- reverted include-guard removal to old routine, because the new one was too error-prone in certain scenarios
- made some minor adjustments to insert blank lines instead of removing them
fixed the call of the analyses 'featurelocations' and 'interaction' (both missed the command-line options)
inserted a reset for several analyses (resets global variables that did retain their old values in the next run of the analysis)
- removed some TODO tasks
- small renamings in comments and for debug messages
