aiohttp template decorator not working when a handler function is used.

[joente]

The current template decorator need a handler to be written from a class.

example:

class Handlers:

    @template('base.template')
    async def myhandler(self, request):
       return {'name': 'Test'}

but the following does not work:

@template('base.template')
async def myhandler(self, request):
   return {'name': 'Test'}

The arguments self and request were hard coded and are now replaced with *args

Created version 1.0.5 containing the bug fix.
