This pull request fixes some syntax errors for building 'messenger.mexa' file.

Hi! Thanks for doing this - to understand these errors: what version of python and what OS are you working on?

Dear @arokem, I am using win xp 32bit with python 3.4.
The first bug is file object not having decode() method. The second is missing a space. The third and the forth is subprocess.Popen().stdout returning byte stream instead of text stream, unless we change the universal_newlines argument in method Popen() into True.

I am worried that these changes will not work on python 2, and I would like
to keep support for python 2 as well. Have not had the opportunity to test
this on python 2 yet. Give me a couple of days to do that.

Sorry for not picking this up before. I think that this was all addressed in #112. Let me know if I can close this. Thanks!
