Subsilver2 is missing the bbcode-helpline for inline-attachments.

The "place inline" button have a missing help tip, actually it display "undefined" :
File affected : posting_buttons.html
Find :

			w: '{LA_BBCODE_W_HELP}',

After add :

		a: '{LA_BBCODE_A_HELP}',

This doesn't happens in Prosiver, where the variable is defined, but never used
