echo wants to battle!

... and holy shit, basically every problem i had with cargo is gone now? i can't believe it??

• target directory can be moved around
• not stuck to the bin/main.rs and lib/mod.rs layout
• workspace members can be anywhere, not just immediate subdirectories of the top-level directory

basically the only incredibly minor issue i have is that it defaults to creating a git repository in every new crate directory, but i can easily delete the empty .git folder it made and carry on with my day (and i wouldn't be surprised if there's some command line option you can pass to turn this off, too; it's an odd default, but as long as i can switch it off easily, it doesn't bother me).

time to see if the language itself lands better this time around...
