SourceMap generation and serving works excepting..

- the template cache url is wrong
- noticed a 'template' directory in generated?
- would be nice to not have to copy these files, possible to just
add another express.static handler to point to app/js and vendor/js?
Removes the need for copy by modifying lineman

- linemans server modified locally to serve both pieces:

app.use express.static("#{process.cwd()}/#{webRoot}")
app.use express.static("#{process.cwd()}")

- this is needed so requests for sourcemap source files go through
- also needed was the sourceRoot property set to '..' so the request
is formulated as /../app/js/* and /../vendor/js/*
- this is potentially hacky? maybe there's a better way
- re-enables proxy, now that i don't need copy
don't need jst in the browser
Reorganizes concat_sourcemap to happen at the end

- fixes changes not being picked up by less compilation.
- also adds support to inline sources via sourcesContent in
grunt-concat-sourcemap
Upgrades grunt-concat-sourcemap to 0.3

- supports sourcesContent!
