Remove user's programming rights requirement by instead using absolute page references

Currently, in order to use the WikiManager application, you need to:
1) be an Admin
2) have Programming Rights

As far as I can see, the 2nd requirement (PR) comes from the fact that, in certain places in the velocity code, instead of using absolute page references like:

$xwiki.getDocument("$subwikiName:XWiki.XWikiPreferences")

... we are using restricted API, changing the database in the context and using relative references like:

$xcontext.setDatabase($subwikiName)
"XWiki.XWikiPreferences"

I don`t know if there are other locations or cases that require programming rights, but from a first look, making the above changes would remove this requirement.
