Runscript 1.3.0 Release Candidate 1

Environment variables!

Environment variables can now be created/overriden in a runscript using bash-like syntax (MY_VAR=value). They are evaluated at the line they are declared, and don't have their values change between command executions unless there's another line with an env override.

There is now a flag to list all the scripts in a runfile (with a fancy colour display too)

Command executions containing interpolated arguments now display the evaluated form next to them

The attached binaries are not installers!
Simply decompress them, and they (should) work. Put them on your $PATH if you want.

No windows build for this pre-release due to a linker error.
