[PATCH V2] New module to set appropriate sys.path for scripts.

[Guilherme Salgado]

This is so that we don't have to write a wrapper shell script for every python
script we have in app/patchwork/bin/.

Signed-off-by: Guilherme Salgado <guilherme.salgado at linaro.org>

This second version just uses the new module in parsemail.py and then removes
parsemail.sh, which is no longer needed.
