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
follows the golden rule
Move install to root dir
* Usage is now ./install, will need to update README as such
Merge pull request #34 from salarkhan/install
