Merge pull request #1 from nicatronTg/patch-1

Added a readme.
Update README.md
Moved team ranks out of extras folder.  Changed it to work more off of Exsto's plugin system rather than making users move it in and out of folders.  It now relies off a variable to work, and will correctly restore old team data after users turn it off.
Re-added !updateowner for those stuck in a listenserver without srv_owner.
Properly fixed the ExPrintCalled hook.  As a result of that, errors are now logged under exsto_logs/errors.
Fixed a few inconsistencies with the variable editor, and fixed deleting environmental variables.
Fixed the head titles plugin to work with the new .png resources.
Fixed mysqloo attempting to require even when mysql is disabled.
Fixed !updateowner not working properly.
Fixed variables not returning that they were accepted.
Fixed menu erroring when it attempted to move notifications that were no longer valid.
Fixed variable changer outputting that variables were never accepted every time.
Fixed various menu errors, and fixed menu recreation on rank changes.
Fixed jail plugin for GM13.
Brought back in chat printing plugin and fixed help menu for GM13.
More error checking in the menu.
