Initial settings structure

Changed the initial settings structure so that iStarter.settings looks
for a config file which tells it which environment it's running in.

I've built a settings file for each of us to modify according to our
own development environments and another couple of deployment envs.

Note, that I'm also using a settings file in the ideasapp so that some
settings stay with the app (for easier portability). The app-level
settings file inherits from the project-level settings file.
Logging setup

Thought I'd get this as good as poss from initial commit. The
project-level settings file contains logging settings. See
ideasapp.views for an example of including logging in your scripts...
Template initial commit

Here are some templates. I've used a base.html - basically extend from
that using the blocks I've built in it. For an example of how to extend
a template, see /templates/ideasapp/idea_submit.html or
idea_thanks.html.
Initial commit of ideasapp and all the rest.

Bootstrap, views, urls, etc
Merge remote-tracking branch 'upstream/master'

first commit of ideas app and settings, logging, etc..
