Bumped haxr dependency to address roscpp compat.
Bumped haxr dependency to address roscpp compat.

Some communication with roscpp nodes was causing trouble for roshask due
to an implicit string type annotation in XML-RPC. According to the spec,
an XML-RPC value such as "<value></value>" should be interpreted as an
empty string. haxr was instead looking for
"<value><string></string></value>" for such values.

I patched haxr to accept unwrapped text as a string value.

Fixes #14
