Commiting the git crime again

This release adds some nifty featues:

• A configurable directory poller interval
• Service recovery when the monitored directory is not writable or absent

It also fixes upgrades with newer configuration files and preprocessed images errors when using the new poller.

As already said, this should be the last pmOCR v1 release.
It will be maintained until pmOCR v2 shows up, written in Python, which should be fairly more easy to maintain than a 2.5K lines bash script ;)
