[For 1.8] Thank You/Like System v3.3.6 + MyAlerts support

[EviLito]

Hello, please consider adding a setting to disable the "alerts" that are displayed right after a post is thanked or "unthanked", for those that don't use the plugin MyAlerts.

I had to remove the following lines:

$.jGrowl(tylSend);
$.jGrowl(tylRemove);

 from jscripts/thankyoulike.js
