New Save and load system - v1.10.5

So, this is another quick update that i decided to release right away instead of combining it into a big one. I'm going to attempt to in the next few days finish this update. Currently the game does have a lot of bugs, so just bare with me while I fix them (and comment about any that you find because I often forget about them). Either way, here's what I  have added:

• Main Menu, allowing you to pick between starting a new game or loading old games
• Complete rework of the save system, allowing you to have multiple save slots and allowing you to name them while saving (WARNING: the game does NOT automatically save, so keep that in mind when playing so you save pretty often so you don't accidentally lose your progress)
• Renamed continue button to advance year (was going to do this originally but forgot, thanks  to the guy who reminded me to do that)

I plan on doing some playthroughs now to see if there's any bugs that I've missed and I'll hopefully fix them, and then I'll get working on the next main content update (: (no spoilers, but it'll help improve combat)
