New Name and v2.0.1

I'm working on rebranding for the Steam release because cardTD was always an "unfinished project" name for the game and the SEO isn't great. There's also been a kickstarter for a similar game with the same name so I'm going for something more unique.

Here's a work in progress of the new name and logo.

I also updated (using the correct channels this time) to v2.0.1 to fix the "you can place all the units" bug. v1.8.1 has been uploaded for those who want to retain access to it.
