      - updates timestamp if the file is dirty (according to git)
    	  This hacks around missing support for
    	    - gitattributes: https://bugs.eclipse.org/342372
    	    - pre-commit hook: https://bugs.eclipse.org/299315
    	  [Update 2017-05-15: EGit now implements smudge/clean filters: https://bugs.eclipse.org/bugs/show_bug.cgi?id=342372#c101
    	   The Eclipse builder and this part of the script could be replaced by Git-native filters now
    	   (if sombody writes a portable filter command that generates the version numbers in the right format)]
    	
      - installs script if
         1. file got modified, and
         2. global Ant property of file name exists (with full OS path to file as value)
            E.g. set property jdtbugzilla.user.js to C:\Users\[user]\AppData\Roaming\Mozilla\Firefox\Profiles\[random].default\gm_scripts\JDT_UI_Bugzilla_Add-On\jdtbugzilla.user.js
