updated local_zoneminder type extension file

**Purpose:**
* support ZM running on CentOS/RHEL 6.x in SElinux ENFORCING mode
* Reference issue #593

In order to support CentOS/RHEL 6.x machines running SElinux in ENFORCING mode, the following type extension file has been updated. Unit tested on Centos and RHEL 6.6 machines. 

**Steps to reproduce:**
1. ZoneMinder running on system with SElinux in ENFORCING mode
2. remove provided compiled selinux module for zoneminder from system
`semodule -r local_zoneminder`
3. Compile new type extensions files
``checkmodule -M -m -o local_zoneminder.mod local_zoneminder.te``
``semodule_package -o local_zoneminder.pp -m local_zoneminder.mod``
``semodule -i local_zoneminder.pp``
4. Refresh ZM page - ZM is now running with selinux mode ENFORCING

**Additional info**
I bumped the modules version integer and cleaned up the formatting of the file. I'm a little unclear on proper etiquette when it comes to contributing to open source projects, if I'm at fault for anything please let me know and I do apologize.
