Quick 1.5.2 hotfix and quicksave beta

Quick late minute update requested by themadspektre on discord.

Possibility to exit from the shop by pressing E again or clicking on the door

A temp-save to "halt" a run temporarily before coming back to it. the save will be removed on "continue" to avoid save-farming and to empower the player to find another shop.
The saving will be avaliable with the fireplace present in the shop.

PLEASE NOTE the save function is still in early development and small bugs like rooms changing sometimes can still be present.
I have released it early to make the burden of "long runs" already easer on the player whilst we'll finish up with the function.
