Attempt to bound type parameter with a nonexistent trait StrAllocating

[MattWindsor91]

On Windows 64-bit, rust-lang/rust 62fb41c32, docopt b5e9e16 I get:

$ rustc --version

$ cargo run -- -d'localhost:1351' -u'localhost:1350'

Could not compile `docopt`.

To learn more, run the command again with --verbose.

While the regex issues are #65, the StrAllocating error seems to be a new one, caused by this prq.

Can confirm issue on Ubuntu 64bit.

Ah, yup. Looks like I'll have to switch to StrExt.

I'll fix this and the regex warnings in a few hours. :-)

Fixed.
