A few changes in handler.py template

[weaversam8]

Hi there, this template is very helpful! Looking forward to building a custom handler!

I noticed a few discrepencies in my generated handler.py, I believe there are some changes needed in handler.py.jinja

• The comment on Line 1 still has Python hardcoded, I believe this should be {{ language|title }}

  Line 1 in 1978f7a

  """This module implements a handler for the Python language."""

• The class name generated will fail if the user enters spaces in the language name. I would have PRed a fix for both of these, but I wasn't sure what Jinja filter to use to transform a name like "Language Name" to LanguageName

  Line 16 in 1978f7a

  class {{ language|title }}Handler(BaseHandler):

Hey there! Looking forward to see what you do with it 😄!

1. Good catch. You're right.
2. Good catch as well. Getting rid of spaces should be easy enough: {{ language.title().replace(" ", "") }} (it's important to use title first, otherwise we would lose any subsequent capital letter).

Would you like to open a PR fixing these two items?
