Cleanup: Eliminated Eclipse project files from version control

+ Once the Maven conversion is done, Maven support in IDEs will handle
  the the integration (m2e in Eclipse)
New: Updated .gitignore

+ Ignore common Eclipse-generated files
+ Retain old Intellij IDEA exclusions
+ Exclude future JRebel config files (rebel.xml)
New: Organized code according to Maven layout
Cleanup: Removed Ant build + unused stuff
New: Added 3rd party JARs that are not in central
New: Organized configuration files and classpath
New: Use GZIP filter from Ehcache

+ The old one is some random unmaintained code.
  Ehcache is actively maintained and very popular.
Fix: Include simile js individually

+ Needs a better solution (yuicompressor doesn't work with m2e!)
New: Initial POM files
New: Use automatic version info
New: Zip distribution generation
Fix: Grouped ddl, versioning into single release profile
Fix: Added missing plugin versions
New: Added names to POM files
Fix: Activate distribution module on release build
New: Version profile + updater script
New: Updated .gitignore

+ Exclude MANIFEST.MF. Eclipse likes to generate these, and we never
  need to include this file in version control
+ Removed obsolete Ant build exclusions
