PW 3.0.50 core updates

[ryan]

This week's version of ProcessWire expands upon our markup regions support introduced last week, and also contains various minor fixes and tweaks. In addition, it adds a $urls API variable which is simply a shortcut to $config->urls. But since this is so commonly called upon, the shortcut can be useful in reducing verbosity in some template files. Meaning, if you want the URL to /site/templates/, you can now use the shorter $urls->templates rather than $config->urls->templates, if you'd like. This also adds consistency with our recently introduced urls() function that's part of the optional Functions API.
