fixed invalid syntax in README example.
Merge pull request #203 from wunderkind2k1/master

Description of three parameter methods for views added
Fix two cases of undeclared variables being leaked into the global namespace,
found by jshint & mocha. Nuked two missing semicolons while I was there.
Ignore .DS_Store and .jshintrc.
Fetch attachments without an encoding so they are returned as Buffer objects.

This means that binary attachment types (e.g., images) can work
properly.
Whitespace changes.

Trailing whitespace automatically stripped by my editor.
Fixed the trivial jshint complaints.

Thus creating potential merge hell for myself, but meh.
