bots and modules are connected

hey

i slowed down gamedev a little for a few weeks, but not to a halt, so here are some results:

- every visual object was redesigned

- bots and modules are now separate objects that connect to each other's signals in godot (see below a snippet of the module code):

- modules have a new UI, with a "play/pause work" button and a "go to mainframe" button (see the gifs below explaining how the bots work now)

the bots work mining/transporting autonomously after you press play, so it's not required to press "go to mainframe" to drop resources

modules are resource-specific, so a module can be an "iron miner" or an "uranium miner", but it won't be able to change their specialty in-game

next in development: the mainframe ui, so the player can connect/create new modules and bots

the ui is already prototyped below, but it's somewhat ugly; i'm open to any ideas anyone might have :)

so far, that's it

see you in the next one
