Add AbstractMarkerFilePresentFileListFilter and Subclasses

When transferring files and polling for transferred files, some mechanism is needed to prevent partially transferred files from being picked up.

A common technique is to write the file with a temporary name and atomically rename it when complete. This is the technique used by Spring Integration components.

Another common technique is write a marker file indicating that the file is transferred. e.g. when foo.txt is completely written a second file foo.complete is written to indicate the file is ready for use.

Add a filter hierarchy that implements this technique.
