Bug 65849 – [Meta] Spell-checking should share the unified text checker path.

• Component: HTML Editing
• Status: NEW

[Hajime Morrita]

Editor class has two different code paths for spell-checking:
One is for (A) using checkSpellingOfString() and checkGrammarOfString(), 
another is for (B) using  checkTextOfParagraph(), the unified text checker available for Mac OS SL or later.
Having this completely different code paths makes it hard to modify spellchecking code.

We could eliminate "A" by providing checkTextOfParagraph() equivalent
which only uses checkSpellingOfString() and checkGrammarOfString().
This emulation doesn't need to be perfect because current "A" behavior 
is subset of "B" anyway.

Such change would hugely simplify spellchecking code.

It's almost green and ready to review!

This change looks large at a glance. But it's almost about removing the redundant code.
What essentially new is TextCheckingHelper::checkTextOfParagraph().
