Add directionality button(s) (BiDi)

[hadaso@…]

In several languages (Arabic, Hebrew, Farsi) text is written right to left. However, inside the right to left text there is often left to right text like numbers, math formulas, or quotes from left-to-right languages (usually English, but not only English...)

To specify directionality either dir=rtl or style='derection:rtl' has to be added to the <P>, <DIV> or <SPAN> tag surrounding the text (ltr direction is the default, but it is sometimes also needed to be set explicitly, such as when an ltr element is nested within an rtl element. Directionality attributes also apply to <TABLE>, and there's also a <BDO> tag defined in HTML 4 for overiding directionality).

What FCKeditor misses and is present in other online HTML editors are two directionality buttons (or one toggle!) that would apply a directionality attribute to the closest <P>, <DIR> or <SPAN> tag containing the cursor (or apply either a <SPAN> tag with dir attribute or <bdo> tag that does the same to the selection).

There's a plugin that somewhat allows this: ​https://sourceforge.net/tracker/index.php?func=detail&aid=1496112&group_id=75348&atid=737639

Actually thinking about it <span dir=ltr> and <bdo dir=ltr>

are a bit different. <bdo> is much stronger, and overides

any implicit directionality. <span> with dir attributes only pushes the directionality to the stack, but elements nested inside can have different directionality, either internal or external. <bdo> is equivalent to unicode directionality override codes, while <span> with dir is just like a unicode directionality change.

The difference is usage is mostly that <span> is suitable when quoting text with directionality different from the sorruonding text that might have internal elements with different directionality, such as when inside an English paragraph Hebrew or Arabic is quoted, and the quote also contains numbers. <bdo> is very useful when including code or math formulas inline. In trhis case absolute control on directionality is absolutely essential!

The new style system makes it possible to apply such kinds of styles. There is inline support for it, for now. We have also included the definition for direction tags in the Style combo. Check out #494.
