This is a refactor of the loader to use in-memory buffers instead of
trying to optimize for memory usage by delaying reads until the last
possible moment. Since charts tend to stay well below 1M in size, this
makes more sense, and is easier to work with.

feat(version): statically link version at build time

fix(tiller): fix install function

fix(helm): stop requiring a values.toml in a chart

fix(docs): fix typo

Because, occur the following error when `createNS` flag is true.
`panic: template: redefinition of template "manifest"`

fix(cmd): rename verbose flag to debug

fix(Makefile): push to gcr using gcloud

Remove a naming conflict with glog which allows for debugging kubernetes
requests.

Charts should not require a values.toml file -- some charts will just be
manifests with nothing configurable.
