Major overhaul: Support non-wine games

* Moved wine support to own template
* Added xpad template
* Added no-x template for games that don't support being started
  on another X.
* Improved ways template functions work together:
    - EXPORT now appends
    - OVERRIDE replaces all the others
    - in game: command 'super' to call the phases of the templates
    - super supports "-r tpl" to remove the phase function of tpl
Use 'super -r' for torment
