EditTableDialog: Make it possible to change the type of existing columns

Browse Source 
Restore the possibility to change the data type of a column of an
existing table - a feature we lost some time ago.

Also change the updateTypes() method to not actually update the types of
all columns when only one can be changed at a time.
