Ensure sys.argv is a unicode literal

[dagwieers]

It appears that sys.argv exposes string literals while our module now
works exclusively with unicode literals. This is problematic for Python2
unicode processing.

This fixes #27

@tamland Can we get this merged? It fixes a real scenario where unicode characters are provided as arguments.

[tamland]

I doubt this fixes the problem. There are lots of string literals in the code, which in python 2 are not unicode but string. If you force sys.argv to unicode you would be mixing string and unicode again.

It fixes te following example in Python 2.7

#!/usr/bin/python

import sys
from routing import Plugin

plugin = Plugin()


@plugin.route('/video/<id>')
def video(id='12345'):
    print(id)

print(sys.argv[1:])
plugin.run(sys.argv[1:])

When running it with arguments: python test.py /video/fööbàr 1

If the calling script is using unicode_literals, this issue does not occur.

Since v0.2.2 import unicode_literals was added, so every string literal is unicode now in Python 2.

Got it.
@dagwieers Could you just add this example as a test case?
