* rename PEAR/Command/Login.php to PEAR/Command/Auth.php
* replace PEAR/Command/Info.php with PEAR/Command/Registry.php (will contain
more commands related to the local registry)
* started working on Frontend table output
- user interface abstraction, making a Gtk installer should only be
a matter of implementing PEAR_CommandUI_Gtk plus a "pear-gtk" executable
- separated code into command classes, able to specify one or more
commands
- no more "pear-get" :-)
* fixed use of PEAR_Config::singleton to avoid object copying
