instead of just spitting it out directly
Also rename all of said functions accordingly, add documentation,
and start trying to make an actually cross-compatible version of
getPortlet() for BaseTemplate...
Output should be structurally the same. All existing attributes for
output elements are maintained; some may have new attribs added due
to more consistent render method (getPortlet). (Essentially, if one
item had it, now they all have it.)
New attribs include:
* id
* lang
* dir
* aria-labelledby

Also delete unused images, since even if something is
somewhere using them anyway (looked, couldn't find
anything), it wouldn't be able to find them in the new
image location regardless.
Wiki.png, magnify, and link are all part of core and have
been for some time.
