CodeSnip Old Code (SVN)

Added extra "3 day" options to update intervals drop down list.
Previously any update frequency in settings file with no corresponding entry in update interval drop down lists was set to 0 (never update) when preferences dialogue was OKd. This no longer happens. This lets users set a non-standard value by directly editing the settings file.

Added flag to indicate that display should be redrawn if one of auto-update frequency check box's value changed. This is because welcome screen, if displayed, needs to be updated.

Replaced check boxes that were used to switch on and off auto-update checking with combo boxes where user can choose a suitable auto-update checking frequency.

New frame providing an "Updates" tab for display in the Preferences dialogue box.
