Changed to use differently coloured textures for bolts and beams rather
than overlaying a colour in code. This will make it possible to later
replace the texture for only one beam or bolt without affecting the
others.
Render a black or white line around the bolts to help them stand out
more.
Finish rendering-tweaks
Fixed bug where certain effects would place their impact particles at
the player rather than at the target when used in beam mode.
Corrected texture reference in LightningBoltRenderer.
Added/fixed localization strings for some of the beam chambers.
