Several minor issues and fixes

[pengchuan-lin-bp]

Hello,

Here are some other minor issues that I encountered while trying out OSS and fixes I used for them.

1. File system monitoring script uses pyinotify, which doesn't work well with NFS (network file system). I modified src/open-semantic-etl/src/opensemanticetl/etl_filemonitoring.py to use polling observer from watchdog instead, but the drawback is that it will no longer be instantaneous anymore without polling constantly. I also needed to list watchdog as a requirement in src/open-semantic-etl/src/opensemanticetl/requirements.txt.
2. In the search page, the black tooltip box that shows up while hovering over file path will cut off long file path strings due to max-width configured by .tooltip in src/solr-php-ui/src/css/foundation.css. I added word-break: break-all; so that the tooltip box displays the entire string without any cut off.
3. In the search page. the sorting option dropdown will have a fourth, repeating option if Newest or Oldest is chosen. I wrapped the last option $sort_other in src/solr-php-ui/src/templates/select_sort.php with <?php if(false): ?> and <?php endif; ?> so that it won't show up anymore.

I hope this can be of help!

Please add a Pullrequest for 2 and one for 3 so i can easier review it and one to add to Contributors in README.md. Sorry not having time for deeper look at 1 these days.

All three pull requests are created. No worries for 1. Since it's NFS specific, I simply wrote it down to help anyone that might need this information.

Thank you for your help!
