Version 3.80.411

• 20 new activities covering fractions, decimals, percentages and ratios - translations required for most languages.
• 4 new activities covering linear symmetry
• the menu has been slightly redesigned - the activity icons now also have an accompanying icon indicating whether the activity is a simulation/demonstration of a concept or if it is a task that needs solving, or something else.
• from this version the game will check for updates and will let users know if a new one has been released - the update will still have to be downloaded manually - can be disabled from the settings in the login screen. This option may need to be hidden before packaging for any distros - will sort it out with next release.
