v0.6.5-2648: more strict html open tag regex
each test can supply vash and runtime path
update contributing with basic style guide
update licenses to 2013
Makefile! Simplified build system!

"building" is now mostly a matter of concatenating files together,
instead of injecting strings between vash.exports.js. vexports.js is now
just literally exports that are concatenated together. The actual
UMD guard is split between support/exports.{head,tail}.js, which are not
completely valid JS on their own.

`support/tasks` has been removed, and replaced with two much simpler
files.

`support/tasks.js` combines the current version with
`src/vexports.js` to populate `vash.version`. This could be replaced
with a bash string replacement, but it feels pretty tricky. It also does
the same with `support/license.header.js` and the version.

`support/version.js` does what `npm version` does, minus the auto-git
commit.

Vows testing has been simplified to use actual shell globbing.
better size stats reporting
New documentation!

Some, like helper/buffer API is still unfinished, but better to get this
out than wait longer. Docs are README.vash, which generates README.md
for things like footnotes, table of contents, auto linked headers, etc.
Slightly confusing, but a neat demo of vash's capabilities, including
helpers: docs/helpers/md.vash is an interesting example/test case for
the precompiled helpers api.
