TPT++ jacob1 519d2201: save ambient heat in saves, and add a warning in the intro text in betas that you can't save publically
TPT++ savask ac66ce3b: Fix the bug where stickmen were shooting LIGH only in one direction.
TPT++ jacob1 864f0e6f: WIFI lines aren't drawn in persistent mode, and are based on current temp, not tmp, so they work when paused
Fix bug in particle allocation checker (particles not marked as free when clearing the simulation), and move free particle list initialisation into Simulation::Clear()
TPT++ jacob1 468e678c: unhide FOG and RIME elements
TPT++ savask 12c471f2: Soap freezing temp is -25C now
TPT++ savask b2045b0a: Fix sign save/topic regex.
TPT++ jacksonmj: Add a way for photons to set the colour of FILT (major version bump required)

Also add some new FILT modes, and make FILT modes affect BIZR and
BRAY colour in the same way as they affect photon colour. Photons
passing next to DTEC will set the colour of all FILT in a straight
line starting from any FILT adjacent to the DTEC (a bit like an
ARAY beam), and the exact colour of the photon will be used for
FILT interactions instead of the colour based on temperature.

FILT tmp=4: red shift, tmp=5: blue shift. Size of shift determined
by FILT temperature. tmp=6: FILT has no effect on photon colour
(possible before by using invalid tmp modes, but here's a supported
method of doing it. Invalid tmp modes should be automatically replaced
in existing saves).

Also, FILT mode is now described in the HUD.
TPT++ jacob1 d38af276: move QRTZ .tmp into .tmp2 and .ctype into .tmp, fixes bug where sparking QRTZ resets .ctype and stops it from growing
TPT++ jacob1 fd586d16: fix bug where when sparks were reset, ctype wasn't
Oops, fix conduction to QRTZ
