style: Remove some wildcard imports

This patch removes an unused wildcard import in http_error. It also removes
wildcard imports in request and responders, replacing them with explicit ones.
test(bench): Add bench entry point module

This script was accidentally ommitted in a previous commit.
fix: Achieve 100% code coverage across all environments

Python 3 was just shy of 100%. Getting it up there required some slight
modifications to the way messages are logged to wsgi.errors, but this
should not break any apps.
test: Only do coveralls on falcon package, and enable branch coverage
test: Omit a few more subdirs from coverage that don't need to be checked
chore(coverage): Try again to get coveralls working
test: Try again to get coveralls to show 100%
chore: Scale falcon.png

This was done to reduce download time for folks browsing to the rendered
version of README.md.
chore: Update .gitignore to ignore VIM temp files
chore: Added pyprism to AUTHORS. Thanks for contributing!
chore: Remove typo from docstring
test: Add simple "method not allowed" test

This patch adds a test to prove that routing is done correctly in the basis
case.
doc: Fix incorrect example for req.get_param() in README.md

As of version 0.1.4, req.get_param() no longer accepts a "default"
parameter. Instead, callers are encourage to use the idiomatic
python "or" pattern. For example:

limit = req.get_param('limit') or 10

Fixes #132
feat: Add ability to pass a dict 'store' to req.get_param

This patch adds an optional 'store' method argument to
req.get_param and friends. This makes it easy to construct
sparse dicts corresponding to query string params, e.g.,
for use as kwargs when calling app functions.

Closes issue #130
fix: Unicode-aware HTTPError response body serialization

This fix changes the way HTTPError details are serialized to JSON so
that Unicode strings are properly encoded; the href is percent-
encoded per URI standards.

Closes #129
chore: Add py3kwarn to tox

Closes #127
refactor: Migrate _percent_escape to util

This change makes it easier to reuse that code within Falcon, as well
as making the function available to 3rd parties.
