fixed issue where horizontal scrollbar was not reappearing when tooltip is hidden/destroyed
Added a $.fn.tooltipster('setDefaults', options) method to override the defaults for all future instances
Added a method to get the value of the first tooltip matched by selector : .tooltipster('val')
Added an init callback function in options
Merge pull request #63 from evangun/functionInit

Added functionInit() for a custom callback to be fired on initial instantiation
Merge branch 'setDefaults' of github.com:evangun/tooltipster into evangun-setDefaults
Moved the instantiation out of the if statement so when setDefaults() is called the plugin can instantiate at the same time
Returning demo tooltipster implementation back to basic
Fixing merge conflict and tweaking a few things
Merge branch 'master' of github.com:ajreiner/tooltipster into ajreiner-master
overflow-x on the body is now reset to what it was after tooltip closes
