patir 0.8.0

[patir](http://patir.rubyforge.org) provides code to enable project automation tasks: * A logging format for ruby's built-in Logger * A command abstraction with a platform independent implementation for running shell commands and ruby code * Command sequences using the same command abstraction as single commands. * Configuration format for configuration files written in ruby. ## Why? We've been using the same things again and again and can't be bothered to code it anew every time. The command abstraction has been used the most, the Logger defaults and formatting the least.
