Jormungandr routing is now modular:
All route files are organised into modules in a "modules" directory.
Modules could be blueprint if need specific templates and static directories.

There is a example in modules which is desactivated by default.

Now the root index is generated dynamicaly instead of hard coded.

Test are updated accordingly
Enabled modules are now configurable in settings.py. Revert formating on instance.py. Module status and description are now in module constructor
Minor fixes. Added log
