Add KaTeX option for TeX math

[katyo]

Solution for #40

• Added --tex-math command-line option:
  • latex for rendering math to images using LaTeX (by default)
  • katex for rendering math in browser using KaTeX
• Added local copy of KaTeX files
• Implemented wrapping math to spans with specific class
• Implemented preparation of document to process math spans in browser

Missing:

• CGI mode support

style note, static foreach is rarely necessary and can hurt compile times for no real benefit, i'd prolly just regular foreach

but since these are small loops it doesn't really make a difference either way.

Of course, I understand. If you mean the function which generates static array named filesForKaTeX, it evaluates in compile time anyway.

Yeah. Just static foreach means the compiler unrolls it, then optimizes it, then runs it... and in a lot of these cases, just running it is actually better.

For large programs, static foreach can get slow quickly.

Still it doesn't matter here just point it out for future knowledge.
