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.

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.
 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.
Merge branch 'master' into logo-white-compress

Another optipng run over png's.

Ran optipng -o7 -fix over all png files. This should make pages load a
tiny bit faster (you can test this with the pagespeed tool on firefox or
chrome).

It might be an idea to add *lossless* image compression optimization
runs to the release process.
Also optimise gifs with gifsicle.

These are the same gif files just after running
gifsicle -b --optimize **/*.gif
Removed hash from "<user> #pushed to branch..." Hipchat notification
Update select branch to GitLab look and explain why this guide is long so people are not discouraged.
Remove deprecated finders
Updated gitlab.yaml.example's issue_closing_pattern to single quotes

… (misused double quotes here)
Better wording of the import instructions.
Move Go specific meta tag after the atom feed code.
Change web_url_without scheme to web_url_without_protocol.
Update kaminari

Revert "Since the git clone code is more efficient now we do not need this warning anymore."

This reverts commit a757c4a24f110aa25ad36dd347d499cf859e4d0d.

While it is true that Grack memory use while sending data to a client
was improved, this does not change the fact that the Git processes
running on a GitLab server will use more memory for large repositories.
 Merge branch 'cloning_is_still_the_same' into 'master'

Git clone performance is still the same
