Allow konsole to store terminal size in the profile.

This removes the profile setting to 'Save window size upon exit'.  Now
it is in the Konsole settings; each profile can now set desired column
and row size.

Konsole Settings->Configure Konsole->General->Use current window size
on next startup:
Enabled - ignores all profile size settings - uses previous window size
Disabled - profile size settings are used - set via Edit Current
 Profile 1st tab

Only new windows will use "new" col/row/size settings.
