Title: Test case and fix for shlex.split unicode bug

When operating on a unicode string in python 2.6, shlex.split returns
a result that does not work with the file constructor.

This causes task includes to fail because python cannot open the included task.

To reproduce this requires a task include that is templated (this is
because the templated string is a unicode result, whereas a non-
templated string is a non-unicode string)
```

>>> import shlex

['a\x00\x00\x00b\x00\x00\x00c\x00\x00\x00']

>>> import shlex
>>> shlex.split(u'abc')
['abc']
```
The proposed fix (coercing the include parameters to string before the
shlex.split) may not be ideal but it does fix the bug for my test case.
