IMPORTANT!!! There is NO backward compatibility changes!!!
I changed inner processes of the extension. Now it can mutate (change) not only attribute but also CSS styles. For example it can make all input fields resizable.

Due to small amount of users of the extension (according Mozilla's count) I don't see a point to make an update algorithm special for the case. Because it demands a time.

That is why IT IS STRONGLY RECOMMENDED to press RESET button on an "option" of the extension and reconfigure the extension again.

Fixes:
1. Fixed a bug when extension could not run if a page was loaded too fast.
2. Fixed a bug when some attributes were doubled in a changes observer code.
3. Fixed a bug when some attributes could not be observed.

Features:
1. Now the extension can change not only attributes' values but also it can change styles.

Features:
1. Opened Shadow DOM page elements support is added. Closed Shadow DOM page elements can not be proceeded yet. If you want to the extension works for Closed Shadow DOM page elements then you can use some hacks to force closed elements be opened elements. Yes, it is not clear for non software developers, and yes use Google to find out what I am saying about. At least until a closed Shadow DOM page elements supporting is added.

Bug fix:
1. Fixed a bug when disabling a spellchecking could be a reason of laggs.

Issues:
1. I used recursion in some place of the extension code. It is a bad practice and it is needed to be replaced by loop in future.
2. As in the previous release the extension can break some sites but it should be a rare case.
