Merge branch 'release/1.3' into develop
Support non-string based input for boolean values
Remove automatically monkey-patching the stdlib with gevent, since it
has some very very bad effects on the requests library
Fixed up object encoding
Fixed up DB Handler to not call the _head method on _get requests. While
this is technically less code-friendly, it improves performance a lot by
not requiring the searches to be done twice
Bumped version number
Merge branch 'release/1.3.1'
