Windows update

Adds open and close window and curtains sounds. As a bonus, also adds a rain on window sound loop as "indoors_rain".

I can't take screenshots of a sound but I confirmed that it works.

Now I also added smashing sounds for all doors made out of wood (success and fail) and windows (success only)

Pretty nice stuff! A few things to change:

• Let's try to organise the folders per sound_type id. So one folder for open_door, one for close_door, one for smash etc...
• door_smash_fail is nice but it could use some more variants, since it's a sound that will be repeated a lot in close proximity it will sound better if it's not always the same exact track each time. That doesn't need to happen in this PR though but that's something to keep in mind
• the credits.txt could use a smidge more formatting by doing one block of text per author, so just need to insert one empty line between different source. Including the license is nice I'll go back to the one I made yesterday to also include that
