login dialog requires tab before text entry
The password field of the login dialog should have default focus so the user
does not have to hit the tab key to start entering their password.

Keyboard navigation keys work in ConnectionFrame (ie Login dialog) and
ProfileDialog so that the user can hit ENTER to move to next screen. Checked
jdk1.3 and 1.4, on Windows & Linux.
Also fixed loss of initial textfield focus under jdk1.3/linux, added button
mnemonics and changed so buttons can be activated by tabbing to highlight them
and then hitting enter, instead of default activation key (spacebar)
