Specify 'type' for '<input>' elements

[fredden]

On devices with dynamic keyboards (like mobile devices), an <input type="number /> will render a number-pad keyboard by default.

This is a recreation of #2 since the default branch had its history rewritten (force push).

Thanks for your contributions! However, we need to support scientific notation for these fields, so the type 'number' is too limiting since the user might need to input the letter 'e'. Are you aware of another way that could mix both?

Sorry for the force push! I wanted to clean up the author/commiter of many commits since I committed using another account unrelated to the game in the beginning of the repo. I didn't think it would affect anyone.

No problem at all; it's your repo! When I ran git rebase, it worked out what had happened without difficulty.

This makes it tricky. I'll have a think and come back to you.
