Implement support for Directory status monitoring
Currently the File Monitor and the ModificationTimeStrategy only support file monitoring. Implement support for whole directories.
- [+FEAT] FLOW3 (Utility): The Files::readDirectoryRecursively() function now supports an optional $suffix parameter which allows for filtering the list of files by a given extension.
- [+FEAT] FLOW3 (Monitor): The File Monitor now supports monitoring of directories. Once a directory is monitored, any change of files or directories within the directory (recursively) will emit a respective signal. Resolves #3736
- [FIX] FLOW3 (Monitor): Deleted and newly created files are now properly detected by the File Monitor after monitoring of whole directories has been introduced. Resolves #3240
- [+FEAT] FLOW3 (Core): FLOW3 will now check and cache its own revision. If the revision changes (due to an upgrade or update from Subversion), all registered caches are flushed automatically. This prevents PHP errors due to non backwards compatible cache structures in newer versions of FLOW3. Resolves #3649
