Fix functions relating YaTeX-beginning-of-environment or YaTeX-end-of-environment. Line indentation by TAB much improved. Functions that work at enclosing environments, YaTeX-enclose-<ENVNAME>, introduced. Functions for enclosing verbatim and equations are supplied. SPC, DEL, +, - in YaTeX-hierarchy buffer. Compensate odd highlighting of hilit19.
