Auto merge of #50 - chrisduerr:v5.0.1, r=jdm

Bump version to 5.0.1

Since #49 updated the freetype-sys version to 0.11.0, this should allow
consumers to make use of the new version without having to manually
update anything themselves.

Since 0.11.0 was just a fix for an existing build failure when building
freetype from source, it should not require a breaking version change.
