added printing of homepage and source to search results. issue #166

added kicker to Gemfile

Found cause of problem with most failures on Travis, the .git directory was removed from the BananaLib fixture tarball.

Which one should normally do, but it won't be available on Travis.

appledoc options

* upstream/master:
  Fix .kick script for Kicker 2.5.0
  Print a template for a new ticket when an error occurs. See #163.

- refactoring
- default options for appledoc
- added command line arguments to pod install
- added option to force documentation generation with appledoc

* upstream/master:
  Update for Xcodeproj HEAD.
  Don't validate the git repo settings, as the installer cleans it out.

(Not sure which is correct behavior, but I assumed this test was wrong)

- introduced '--generate_documentation' '--install_documentation' command
  line options
- only doc installation/generation only if pod does not exists
