Forking repos will fail in some situations because of this issue.
Whitespace fixes to patch
Reduce image size.

Checking the site with the PageSpeed extension, one of the reports was
in reducing image size.  This reduced the number of bytes by 67%.

It was done with optipng -o7 -fix *.png in the app/assets/images dir.

add rake gitlab:import: all_users_to_all_groups and user_to_groups

I opted for admins to be added as "owners" instead of "masters" because project masters can managers members, but only group owners can manage members.
Allow public repo searching

GITLAB-1386

Change-Id: I9a0bbe8db1a9bb00cef33b3e1854d78844b70a45
Updated convience method to private
Fix #5313 hipchat 0.14.0 to use http_proxy
Add comment about tls for ldap method

`omniauth-ldap` also supports tls for ldap method
Fix HTTP push to public repos

When doing an HTTP push, git (as of v1.7.9) first do an info/refs
request, and only if this request requires authentication it asks the
user for its password and authenticates further requests.

The initial request normally clears without auth on public repos as it
doesn't update any ref. This patch forces every git-receive-pack
requests to provide authentication.
Update installation.md

Updated the version of Git used in the section for compiling Git from source.

Also, changed the verbiage used in the section "Initialize Database and Activate Advanced Features". It previously said to type 'yes' to install the database.
Postgres Client Needed for Ubuntu 13.04

It looks like the postgresql-9.1 package didn't include the actual client. Needed to install it separately to get this to work.
refactor omniauth configuration method

This refactoring allows a user to use omniauth providers which do not
use ```app_id``` and ```app_secret``` without needing to change the
devise configuration.
 Added support for Go's repository retrieval.

 - Simply adds the releavant meta link in the project's show action.
 - Information about this meta tag can be found here:
   http://golang.org/cmd/go/#hdr-Remote_import_paths
Use project methods instead of attributes.

- This should work correctly in all cases now.
- Added a new project method that returns the web url for a project without
  the scheme prefix.
Use web_url for web_url_without_scheme.

- Previus version was still incorrect as it ignored cases where GitLab would
  be installed in a custom location.
- This assumes that if this method can be calle, web_url will return a valid
  URL.
