Rewrite of machine code

- The most common attackbys now use a common proc and a flag system

- The following flags now exist : EMAGGABLE, SCREWTOGGLE, CROWDESTROY, WRENCHMOVE, FIXED2WORK, EJECTNOTDEL to define different behaviour using the machine_flags var

FLAG EXPLANATION:
- Emaggable is self explanatory
- Screwtoggle is if it has a maintenance panel to open and close (or for computers, if you can screw the monitor off). Setting this makes the machine call togglePanelOpen when hit by a screwdriver
- Crowdestroy is if you can decon it when the panel is open. Setting this will make the machine call crowbarDestroy if hit by a crowbar while the panel is open
- Wrenchmove is if you can use a wrench to move it around. Setting this makes the machine call wrenchAnchor
- Fixed2work is if it needs to be anchored to call attackby
- Ejectnotdel is if it ejects any contents items instead of just deleting them (fridges use this)

Machines now use flags appropriately added with inherited procs to replace copied code
- Should make adding these features to new and current machines a lot easier, since all that's needed is to inherit attackby all the way from obj/machinery and add the right flags
- Also fixed some relative pathing in edited files, anything I edited should now be absolute
- This is by far not the complete list of edited machines. I can put more work in to try and check them all, but this is a lot. What's most important is the functional changes.
- Changed a door problem of windoors have a stupid number of path variants: there are now only windoors with variables

CURRENT LIST OF CHECKED AND VERIFIED MACHINES (LAST UPDATED 24/09):
- Vendors of the vending type e.g. sale machines, department vendors
- Autolathe
- Smartfridges (now with special circuits), all kinds (with contents ejecting)
- Hydro trays and apiaries, biogenerator, seed extractor
- Shield gens, all kinds (also edited shield gens to not require a dir check on capacitors)
- Singulo engine machines, including rad collectors, emitters, field generators, etc
- Research machines: protolathe, decon, imprinter, fabricators (now with material removal)
- Cooking machines: food processor, grinder, microwave. Wrench movement with all other cooking machines: fryer, oven, grill, candy machine, cereal maker
- Chemistry machines: Chemmaster, grinder, chem dispenser
- Pacman generators, including the unloading of fuel when deconned
- Teleporter machines in the teleporter room
- SMESs
- WORKING ON: None right now
