i/64: The inspector should render the RTL content in the trees properly.

Fix: The inspector should render the RTL content in the trees properly. Closes #64.

I'm not sure if the change is visible enough (at least to me):

1. Moving caret left (advance to the end of a text node):

2. Moving caret right (advance to the beginning of a text node):

3. Jumping from right to left using home and end

This is the most outstanding "issue" for me - the CKEInspector "Model" panel is LTR while moving a caret to the boundary of an RTL text node occurs as a jump of a selection - while technically it is correctly rendered at the beginning of a container and before text node.

Now, I've tried to change the whole Model view to RTL:

... and I don't know - looks awkward (as any RTL text) but the "jump" feels a bit more natural now.

ps.: The closing element, like </paragraph> is rendered as <paragraph/> (the / is rendered as in RTL) currently - feels OKish in RTL model view.

So, after @oleq guided me to the "compact text" option, the PR looks pretty well and it is not so confusing. The jumping comes from the way how RTL is displayed in LTR nodes so we can't do much about it.

Besides my inability to click "compact text" everything works nice. 👍
