Option name misspelled

[mindscratch]

The option name for "boostrap" is misspelled, it is currently "bootsrtap".

It looks like there are only two places in the javascript:

• https://github.com/vedmack/feedback_me/blob/master/js/jquery.feedback_me.js#L136
• https://github.com/vedmack/feedback_me/blob/master/js/jquery.feedback_me.js#L227

The readme and example pages also use the misspelling, not sure if it's anywhere else in the code.

Fixed in the code/readme/example.

Thanks @mindscratch for noticing...
