Memory Bug fix and Reco+Valentine's Mom weight events

Hello! Today's update comes with a fix that should address the Memory hog nature of RPG Maker MV's use of parallax images (backgrounds).

Alongside this fix is the addition of Reco and Valentine's Mom's weight stages! However, the last two stages  of each character currently have placeholder text. The text will be added by tomorrow 7AM (PST)!

I moved a lot of images around in the code to address the Memory hog bug, so there may be some images jumbled up in-game! 

I will continue to test this tomorrow before moving on to working on the next update!

Throughout an extended play session, the game should no longer increase Memory usage by a drastic amount on computers with less than 16GB of Memory, however you could technically still crash yourself if you spam open the Shop Menu. This is a limitation  of the game engine, so I don't recommend doing this.
