BIDI: Missing support for Arabic (Arabic Indic) numeric digits in CKEditor

[edithk]

Digits are represented in the editor by Hindu-Arabic digits (0 1 2 3 4 5 6 7 8 9 ) even for Arabic locals, without the option to convert them to Arabic-Indic digits (٠ ١ ٢ ٣ ٤ ٥ ٦ ٧ ٨ ٩).

We suggest to leverage on the style combo mechanism and add new styles, similar to the Language: RTL and Language LTR styles:

'Numeral: 123'

'Numeral: ١٢٣'

When 'Numeral: 123' style is activated on a selected text --> the digits in that text will be converted to Hindu-Arabic digits.

When 'Numeral: ١٢٣' style is activated on a selected text --> the digits in that text will be converted to Arabic-Indic.

I will attach shortly a link to a pull request with a patch code for your review.
