#79 Forgot about key on cancel / forget conn speed at setup

[shockzor]

When first installing Waste it asked me
about "Connection Speed", I picked "T3/LAN", then
when I opened the preferences dialog, it was not saved.

In the preferences dialog, under the "Private Keys"
menu, when I selected "Reload private key and
password..." then chose to "Cancel" it grays out the
options and forgets about my key.

By the way, tool tips for the "WASTE Preferences"
dialog would be nice.

Checked in a patch for this fix too. Other than the tool
tips request this bug can be closed.
