[ANN] Sinatra 0.3.0

[Ryan Tomayko]

We haven't published a gem in a little over four months. There hasn't been a
whole lot of crazy new features but there has been a significant amount of bug
fixes and code refactoring, so we've pushed out an 0.3.0 gem based on the
"next" branch plus some additional cleanup and fixes.

Please take sinatra-0.3.0.gem for a spin (it should hit the rubyforge gem
servers sometime tonight) and report any issues here, in lighthouse, or on
#sinatra.

Here's a quick summary of changes since the 0.2.2 release:

* Add sinatra.gemspec w/ support for github gem builds. Forks can now
enable the build gem option in github to get free username-sinatra.gem
builds: gem install username-sinatra.gem --source=http://gems.github.com/

* Require Rack 0.4; removes frozen rack dir.

* Basic RSpec support; require 'sinatra/test/rspec' instead of
'sinatra/test/spec' to use. [avdi]

* before filters can modify request environment vars used for
routing (e.g., PATH_INFO, REQUEST_METHOD, etc.) for URL rewriting
type functionality.

* In-file templates now uses @@ instead of ## as template separator.

* Top-level environment test predicates: development?, test?, production?

* Top-level "set", "enable", and "disable" methods for tweaking
app options. [rtomayko]

* Top-level "use" method for building Rack middleware pipelines
leading to app. See README for usage. [rtomayko]

* New "reload" option - set false to disable reloading in development.

* New "host" option - host/ip to bind to [cschneid]

* New "app_file" option - override the file to reload in development
mode [cschneid]

* Development error/not_found page cleanup [sr, adamwiggins]

* Remove a bunch of core extensions (String#to_param, String#from_param,
Hash#from_params, Hash#to_params, Hash#symbolize_keys, Hash#pass)

* Various grammar and formatting fixes to README; additions on
community and contributing [cypher]

* Build RDoc using Hanna template: http://sinatra.rubyforge.org/api/

* Specs, documentation and fixes for splat'n routes [vic]

* Fix whitespace errors across all source files. [rtomayko]

* Fix streaming issues with Mongrel (body not closed). [bmizerany]

* Fix various issues with environment not being set properly (configure
blocks not running, error pages not registering, etc.) [cypher]

* Fix to allow locals to be passed to ERB templates [cschneid]

* Fix locking issues causing random errors during reload in development.

* Fix for escaped paths not resolving static files [Matthew Walker]
