.crab extension

[trvswgnr]

this changes the file extension that cargo looks for (and uses in cargo new) from .rs to .crab. used with the renamed toolchain this can also be used with crabgo.

it currently needs to be built using the existing upstream cargo command. this isn't ideal, but to fix would probably require adding the ability to use both .rs and .crab, which would a more intense task.

to test:

/path/to/cargo build --release
/path/to/target/release/cargo new hello

for whatever reason, building cargo directly allows it to be renamed, where the normal install script does not. so doing this:

cp /path/to/target/release/cargo /path/to/.cargo/bin/crabgo

works fine and allows crabgo to live alongside cargo.

this resolves crablang/crab#20

LGTM ! ✅

what about .🦀 crablang/wastebasket#11

I think that it is way much easier & faster to write crab, than to search for an emoji, imo.

purr @Lissy35 on crablang/crabgo#11

I mean, if Mojo can use the .🔥 ext, then crab lang should deffo jump on the trend with the .🦀!
