Make new/run/pov/disp are now configurable when invoking make.

Example:
make NAME=lcdframe D=0.8 TOP=front BOTTOM=back new

- solidify/Makefile (new, run, pov, disp): test run targets can now be
  configured by setting make variables on the command line
- solidify/main.pov: renamed to template.pov and changed all occurrences of
  "batcvr" to "NAME"
- solidify/Makefile: generate main.pov from template.pov
