Radiation Collector analyzing

Checking a collector's last power output via analyzers has been moved to multitools, because that actually made sense (betcha didn't know this existed, I know I didn't)

Analyzers can now be used to check the gas level of the tank in a loaded radiation collector (yay no more crowbars)
You can also use them on pipes to check gas levels (yay no more pipe meters)

Codewise, the several inconsistant instances of the attackby analyzer code have been moved to a single proc. The following have been converted to use this:
-Pipes (they didn't have this before. Also changed the attackby code to be less dumb...)
-Pipe tanks (you know those big ones in maint everyone forgets about)
-Portable Atmospherics (canisters, air pumps, scrubbers)
-Flamethrower
-Tanks
-And now collectors
