Give - Fee Recovery 2.2.0

* Fix: Store the total donation in `data-total` attribute in non formatted way for more accurate totals when using various currency formats.
* Fix: [give_totals] now properly displays the income of multiple forms without the fee recovery income so that it properly reflects how much is going to the cause.

* Tweak: Improved how settings are saved so that admins don't accidentally save "0" as a percentage unintentionally.
* Fix: The give_get_fee_earnings()" function was incorrectly returning "0" rather than correct earnings.
* Fix: Resolved conflict with Recurring which caused renewal donations to be associated with an incorrect donation level if Fee Recovery is active.

* Important: Added compatibility with Give 2.2.0+. Please update Give Core to 2.2.0+ prior to this update.
* Fix: Resolve "give_global_vars is not defined" error in Chrome developer tools' console log.
* Fix: Added auto width CSS to the fee recovery checkbox to improve compatibility with some theme styles for input checkboxes.
* Fix: Unescaped characters warning was displaying in Chrome developer tools' console log.
