Bower support for anvil
Adds bower commands to anvil (somewhat redundant, you could just use bower...) and attempts to move resources from the package into package specific subfolders under ./ext in the output directory.
Bower and TJ Holowaychuck's Component tools are incompatible. If you're installing components using Holowaychuck's component, then pretty much all the bower commands break. This has nothing to do with anvil; please don't report the issue to me :)
Really the only advantage here is not having to have bower installed globally. To issue any command, you just type "anvil bower [command] [args]" and anvil will pass the task on.
If you want Anvil to auto-install your client dependencies, you can list them in your build file like this:
"anvil.bower":"dependencies":"backbone""underscore"This extension will check for the presence of these packages before each build and ensure they've been installed.## ProblemsUnfortunately not everyone follows the same conventions in their package.json or component.json files so there's no predictable way for anvil to know where to find the component's resources. If there's no folder under lib/ext for a component it's because the author failed to specify; please feel free to let them know they're doing it wrong## Installationanvil install anvilbower
