build.sh is dependent on cwd

[ianb]

If you call build.sh from another directory, r.js can't be found.

One solution for bash is to use $BASH_SOURCE, like HERE="$(dirname $BASH_SOURCE)"

At least testing that r.js exists would allow for a better error message.

Related to #48, needs more context on where build.sh comes from, I do not see it in the volo tree, perhaps a specific use of volo in another project is in play?

[ianb]

I simply did volo create test-project and that created test-project/tools/build.sh – I'm not sure where it came from.

Ah ok, looking at the output from that command, it came from https://github.com/volojs/create-template/zipball/master. I'll move the bugs over there. I'm updating that one now anyway.

This is resolved in the template now by using a volofile to run the build. That way it will work on windows too. volo build from within the created project will do it for any new projects created from that volojs/create-template template.
