Visual upgrade of the installer based on Bootstrap

I am working on mockups for the installer. I'm not ready to rewrite the whole thing, but in the short term I can make sure it looks more up-to-date than the original MrTheme design. I'm still making mockups before I will start updating code, but this is where I'm at at the moment. I have the mockups available at https://beta.impresscms.eu/install2/index.html at the moment. Have a look around and give me your feedback.

Progress update : the base design is running, and I'm currently implementing the specific changes that are remaining page by page, while testing that the functionality remains. Currently, I'm stuck at the paths page - you can't create a trustpath.

I think this will be ready for test in a few days. PR will be incoming soon.

It's looking good, David! I wasn't able to get past the DB connection page in the mock-ups, I'm not sure why.

Looking forward to adding this to our upcoming release.

Probably because I didn't get further than that page on the mockups. I've been trying to get it to work in an actual installer, and I've gotten as far as the creation of the admin user at the moment. So it's proceeding in the right direction. 

I still have the work we started to update the installer which was mostly a single page.

Would that be the feature/impresscms_2.0-installer branch?

Yes, that was it. I think that was prior to the all the disagreement over the refactoring of the UI and assets. There is another branch that was based on the 'retro' branch that came out of it. https://github.com/skenow/impresscms/tree/features/installer2.0

I put this one temporarily on hold, so I can help get 2.0 out the door.
