John Chilton 292be5b364 Rework interface between jobs and tools. ...

Pull code out of job wrapper and tool for building and evaluating against template environments and move them into a new ToolEvaluator class (in galaxy/tools/evalution.py). Introduce an abstraction (ComputeEnvironment) for various paths that get evaluated that may be different on a remote server (inputs, outputs, working directory, tools and config directory) and evaluate the template against an instance of this class. Created a default instance of this class (SharedComputeEnvironment). The idea will be that the LWR should be able to an LwrComputeEnvironment and send this to the JobWrapper when building up job inputs - nothing in this commit is LWR specific though so other runners should be able to remotely stage jobs using other mechanisms as well.

This commit adds extensive unit tests of this tool evaluation - testing many different branches through the code, with and without path rewriting, testing job hooks, config files, testing the cheetah evaluation of simple parameters, conditionals, repeats, and non-job stuff like $__app__ and $__root_dir__. As well as a new test case class for JobWrapper and TaskWrapper - though this just tests the relevant portions of that class - namely prepare and version handling.
