Update 0.4.10

+Added company presets, so players can save many different companies and select them when joining the game. This also means players can rejoin the game and play a different company if something goes wrong.
+Added the ability to set what AI difficulty and personality different companies will have when a player is not playing as them (though AI is not currently functioning)
*Fixed the new week popups covering each other when ending the turn quickly
*Nodes will now start the game owning 50 of their own shares as a way to dilute shares initially (player ownership always supersedes this)
*Fixed buying shares under 51 being a way to pump and dump a node, this was because share dilution was being capped to 51 minimum
*Changed tooltips from a transparent blurred background to an opaque background
*Fixed share orders starting at the value of a previous order instead of starting at 0
*Changed the colors of the Buy Controlling and Sell All share buttons to better avoid accidental clicks
*Fixed highlighted tiles not returning to normal when placing routes
