Fixed successful creation message
On OSX install the Pear phar would fail if there was a .pearrc file already on
the system. Inorder to fix this, I put in functionality to move the .pearrc to
.virtphp_pearrc and then change it back once the pear phar is done installing.
There was also a bug where the phar location wasn't being set right due
to new environments being created in ~/.virtphp.
Fixing quotes so the new line would not show as output text.
