Fixes noob mistake of setting user.name to an email
Add default author name to set-author-committer to avoid fatal error
* Without it, git commit will use the email to search for an existing
author. If that author doesn't exist, it throws a fatal error
Merge pull request #31 from salarkhan/default-author

Set author name in git commit to avoid fatal error
Move setting of author & committer to post-commit hook
* Exporting variable to the git subshell prevents post-commit from
triggering itself.
* --allow-empty flag allows empty commits. (The first line of defense
against empty commits already runs when the commit is first attempted)
* --no-edit flag prevents text editor from firing up to edit the
commit message ( which is where the author gets amended )
Rename pre-commit file to post-commit
Update README to include example git session
Add install script to symlink pear to usr/local/bin
Fix pear_dir using readlink to access 'true' location of symlinked dir
Don't use readlink when looking for pear_dir in create-hook-file
* pear is a symlink, so there you need readlink. however, in
create-hook-file, it's "context" is OG directory, so there's no need
for readlink
Include installation instructions
Swapped the order of images.
