Merge pull request #81 from Havenwood/version

Added CHRUBY_VERSION constants.
Use ruby-1.9.3-p374 for testing.
Initially set RUBIES to (), to avoid double loading of chruby.sh.
Unset RUBY_VERSION_FILE when loading auto.sh

Ensure that chruby will be called or reseted after auto.sh is loaded.
This fixes a problem when for example a new tmux window is opened and
environment variables (including RUBY_*) reserved, but PATH is reset in
.zshrc/.bashrc. The root cause is thus same than in #46.
Fixed the Arch Linux Install example (@maxmeyer).

Drop shebangs from bug_report and test scripts

At least `[[ ]]` and arrays are not Posix shell compatible.

the current SHELL.

The only exception is `test/runner` that uses bash by default,
as it is normally used via make that uses /bin/sh otherwise.
