documentation/README: Point gox link to correct repository

website: document chroot running process gotcha

readme: add a note about the gox dependency for compiling

README/developing packer: Mention the bazaar requirement.

Mention the bazaar requirement.

https://launchpad.net/tomb is the only package which uses bazaar so far.

I thought about putting it in compile.sh or devcompile.sh, but then
I realized if gox changes upstream it will be buried and potentially
confusing to update. Hence including the `-u` in the readme for
`go get`.

website: Match default ec2-bundle-vol documented on the website to the one that's used by the code.

Issue #248 contained a PR which changes the way bundle_vol_command is
used by default. This change to the defaults was not reflected on the
website, so I encountered the same issue when making changes to the
bundle_vol_command in my config.

website: typo in vmware docs' YAML front matter

[GH-635]

added post-processor-vsphere

builder/vmware: Path related fixes in esx5 driver

/cc @matheeeny - Tests :)

/cc @matheeeny - I prefer to be more explicit and say this is the path,
rather than the secret value itself.

provisioner/chef-solo: add support for chef-solo encrypted data bags

/cc @rasa

post-processor/vagrant: skip gzip compression if compression_level=0

website: fix run-on italicizing for description of data_bags_path

underscore of "data_bags" should be escaped; causes run-on italic

Adds additional option to chef-solo provisioner for an encrypted data bag
secret file.  Local file is copied up and referenced in solo.rb
