Add escapecss filter (#3546)

Browse Source 
* add escapecss filter

this filter would allow creating valid css classes from titles containing special characters

we assign a class to an element using `encodeuricomponent[]` so that the class name is encoded

in a stylesheet we create the classname by `<title>escapecss[]` which applies the uri encoding and escapes characters that need to be escaped

* Update encodings.js

* refactor tagToCssSelector, add escapeCssSelector

* use escapeCssSelector

* escape using CSS.escape if it's available

* Update encodings.js

* revert factoring out escapeCssSelector
