make it possible to precompile the views (#94)

We don't have the `Template` object at compile time, so we now use another module to store shared settings. Also, the helpers no longer depend upon `Template`.

This reverts commit c733a3568aaa22c0aa6dddaf7d07f8f6556bb703.
precompiled template support (#94)

Run `gulp compile` to compile the templates.

Everything should still work fine without the precompiled templates.

For now, I'm putting the precompiled templates in .gitignore--they only speed things up a little, and the template is still changing rapidly. Eventually we'll need to commit them, though.
