Adding dyncall 0.7 archive

This is merely a step to ensure access to the archive.

Modified: .gitignore
Added: src/dyncall-0.7.tar.gz
Added error catch

unbuffering should check for a null pointer as this could prevent a lot of "mysterious" errors from cropping up.

Modified: src/include/jsh.native.c
Status update

The repository is in an initial 'demonstration' state

Modified: README.md
