improving the support for simple Template Engines
added some examples of simple web apps using Micro. This is also a playground
removed an incomplete example
forgot to commit the test covering the newly added ViewRenderer `evaluate` method. This is for Markdown.
added another example app covering miscellaneous Micro functions (incl. a small Freemarker snippet)
upgraded to Freemarker 2.3.21 and updated corresponding license info
implemented the 'evaluate' for the Freemarker template engine. Now we're covered, the View developer can go wild :)
updated the simple micro web app generator components; using the $yield context object in the default template and misc. minor code cleanup
