A few changes to allow development on conts/test directory.

Now, bare containers get their files from conts/bare_src instead of conts/test.
test directory will be used for the next generation test programs.
Also bare_src is tracked by git now with a minor mod to .gitignore.

conts/bare_src/hello.c
