Removing docs for mounting multiple apps.

Mounting multiple Dancer apps via Plack::Builder is broken, has always
been broken, and will not be fixed in the near future. We should not
encourage this approach by documenting it.

Removing docs for mounting multiple apps.
Don't add meaningless 'encoding' to TT config.

When scaffolding an app, don't add a meaningless 'encoding' setting to the
example T::T config - it won't do anything, and is misleading.

The actual setting is 'ENCODING', and that gets automatically added based on the
'charset' setting.

Change regexps using { to have { escaped for compatibily with perl >=5.17

Solves gh #872
Reduce dependence on %ENV for internal code.

Perl 5.17.3+ changes behaviour of `%ENV` so values are also stringified.

This change aims to solve that ( gh #870 ) by replacing %ENV based code with
a passed around local hashref, that is passed as the last parameter to `new_for_request()`
instead of relying on the data being passed around via `%ENV`.
