Do not return an error if no matches found

chore(docs): add chart repository docs

do not return errors and do not print any messages about no matches found to be more like unix commands

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.
