Use editor.lang.common in the iframe (flash, image) dialog

[Wiktor Walc]

We have introduced a new dialog that contains words that are already used in other places:

• Width
• Height
• validateWidth / Height
• Alignment options

To reduce the size of language files and make the fresh release of CKEditor looking better in languages other than English (getting new translations from contributors always take some time), let's do some cleanup with the common words we have used there and ensure that those strings would be translated correctly in 3.5.

Note that the context in the Flash and Image dialogs is exactly the same for those strings, so we're safe with reusing those values.

Note that this patch does not cover all the changes that could be made to reduce the size of language files. We'll do it in CKEditor 4.x. It just takes care of words described in the ticket. The iFrame dialog should look now better though.

lang.common language entries were created in the following way:

CKEDITOR.lang['{$lang}'].common.width = CKEDITOR.lang['{$lang}'].image.width;
CKEDITOR.lang['{$lang}'].common.height		= CKEDITOR.lang['{$lang}'].image.height;
CKEDITOR.lang['{$lang}'].common.align = CKEDITOR.lang['{$lang}'].flash.align;
CKEDITOR.lang['{$lang}'].common.alignLeft		= CKEDITOR.lang['{$lang}'].flash.alignLeft;
CKEDITOR.lang['{$lang}'].common.alignRight		= CKEDITOR.lang['{$lang}'].flash.alignRight;
CKEDITOR.lang['{$lang}'].common.alignCenter		= CKEDITOR.lang['{$lang}'].table.alignCenter;
CKEDITOR.lang['{$lang}'].common.alignTop		= CKEDITOR.lang['{$lang}'].flash.alignTop;
CKEDITOR.lang['{$lang}'].common.alignMiddle		= CKEDITOR.lang['{$lang}'].flash.alignMiddle;
CKEDITOR.lang['{$lang}'].common.alignBottom		= CKEDITOR.lang['{$lang}'].flash.alignBottom;
CKEDITOR.lang['{$lang}'].common.invalidHeight	= CKEDITOR.lang['{$lang}'].flash.validateHeight;
CKEDITOR.lang['{$lang}'].common.invalidWidth	= CKEDITOR.lang['{$lang}'].flash.validateWidth;

By checking all the language files it turned out that lang.flash entries are correctly translated in almost all places.

Putting an invalid value for the height or width fields in the iFrame dialog does not trigger the alert.

Fixed with [6207], updated translation status with [6208].
