osTicket NoteFirst Plugin

Ensures that when you view a ticket, the "Post Internal Note" tab is highlighted where possible.

To install

• First: install https://github.com/clonemeagain/attachment_preview as this relies on it.
• Then download/clone this into your /include/plugins directory as a directory
• Then visit /scp/plugins.php to install & enable it.

Should work with 1.9+ Please test and let me know. Conceivable that it works with 1.8, if that is still around.

Can be made much simpler, if you are willing to change core a touch!

• Edit include/class.osticket.php
• Go right to the bottom to the "start" function, add at the beggining: global $ost;
• Effectively, apply osTicket/osTicket#2907
• Now we don't need the attachments_preview api! :-)
• Now just rename the bootstrap method to "old_bootstrap" and the "new_bootstrap" method should be renamed "bootstrap"

I've subscribed to that pull-request, so I'll update this when/if that get's merged.
