Merge branch 'update-bootstrap-and-make-responsive' into 'master' ...

Update to Twitter Bootstrap v3 and make responsive

Fixes #29  
Fixes #42  


Changes include:
* update bootstrap and jquery files
* add new filters for bootstrap 3 usage
* adapt templates to bootstrap 3
* use for loops instead of repeating code in the templates
* change per address preferences to a row based form
* make responsive
* change wells to panels

Note for proper styling of error-alerts a modification in the settings is needed.
This is because the error class was changed to danger in bootstrap 3.
These lines need to be added:
```
from django.contrib.messages import constants as messages
MESSAGE_TAGS = {
  messages.ERROR: 'danger'
}
```
