Start preparing for next version of FW/1.

Update Clojure version. Add :url / :license.
Update example main function
Clean up requires and config declaration
No longer :reload-all - it can affect 3rd party libraries in unfortunate ways. The correct approach would be to test (fw1/reload? rc) in the global :before function and perform any specific reloading you want. Note that reload only affects a single controller anyway (and, previously, its dependencies) which isn't a great approach anyway.
Add Selmer, bump version to 0.2.0
Add Selmer templated version of the example
Update example to better support Selmer templating and do a general code cleanup
Add support for Selmer templating
Update readme with information about Selmer
