[e-lang] Ecru 0.1.2 released

[Allen Short]

I've released a new version of Ecru, available here:
https://launchpad.net/ecru/+download

This version makes less use of Python's ctypes FFI for the REPL and so should be more stable in interactive use.  I've also added some missing methods and so this version is able to run most of kpreid's E benchmarks (as described in this message: http://www.eros-os.org/pipermail/e-lang/2007-November/012362.html).  Equality comparison of non-ConstList Selfless objects is still missing, so I've changed the comparison tests to use lists instead of maps.  Here are the benchmark results:
