This will fix the name conflicts we were having before. It's a major
breaking change, but it should fix our problems which is nice. This
closes#6 and bumps the version to v1.0.0.
We had problems with format parameters dispatching (`cwritefln` ended up
calling `format` with '\n' as a trailing - orphan - format parameter),
`format` not being imported from `std.string` and an infinitely
recursive template case for the overloaded `cwritef` function.
This also bumps the version to 0.2.1.
