NOTIFICATION MODAL: MODAL MARKUP

Removed classes:
	- .right-pane-wrap-actions
	- .initialstate
	- .error

Removed CSS:
	- #right-pane-wrap {border:1px #ddd solid;}

Removed unecessary z-index from right-pane error and loading message DIVs.

Raised specificity of element IDs called from jQuery, to reduce risk of potential namespace conflicts, e.g:
	#loading -> #right-pane-wrap #loading
	#errormsg -> #right-pane-wrap #errormsg

NOTIFICATION MODAL:COMMENT DIVS

Replaced:
<div class="up-triangle"></div>
<div class="up-triangle2"></div>

With:
<div class="triangle-fg"></div>
<div class="triangle-bg"></div>

The CSS is identical in rendering the triangles, but the method of positioning them has been adjusted from absolute values and top/left coordinates, to relative ones, using margins; since they're meant to overlap (and create an outline effect), the .triangle-bg element has been given _negative_ margins, allowing it to occupy the same area as .triangle-fg.
They've also been given explicit z-index values to place .triangle-bg behind the comment DIV, and .triangle-fg in front.

NOTIFICATION MODAL: LOADED CONTENT

added classes to expArticle.php:
	.artImg
	.userImg

Made other changes to this expArticle.php template; because it's particular to the notifications view, the modified code will be moved to a new template, notifArticle.php, and expArticle.php will be rolled back to the current master branch for the time being, until the effects the modifications may have, on other site features that use the template, are explored.
Added templates/notifArticle.php, which is a modification of expArticle.php (the latter will be rolled back in the meantime).
Notification code will be modified to use this new template name.
