fix return type on state getters

add string + int context helpers

BREAKING: Modified handler types to allow more flexibility. It may me…

…an you have to change your handlers slightly. Sorry, but it's for the best.

Modified static handler to return appropriate mime types.
Added logic to check directories for index.html files when attempting to serve a directory.

refactor other areas emitting errors

minor consistency tweak

update subdomain matching logic and add caching. fix test issue

Improvements to various areas (#7)

Context handler now has a custom context object to manage the flow of data better when chaining, etc
Added more convenient access to http methods
Added route grouping and sub-grouping
Better subdomain mapping
Filter optimizations

The handler changes are most likely breaking if you've used goro before. It's a better change for the future.

Details:

* add sub grouping
* chain fixes. router fixes. wip - new tests
* chain fix
* fix group nesting issue. alter chain to use HandlerContext for state. filter updates - now runs before and after
* tidying
* add state getter. duh
* add clear state. duh duh
* fixes and enhancements
