Trevor Parscal a564f81aa7 JSHint: Added dotfiles and fixed tons of linting warnings.
* "onevar" warning sometimes solved by just merging var statements
  other times solved by making it a function declaration instead
  of a function expression.
* Also fixed several '_this' variable names in ve.es.Surface to
  more descriptive names, and enabled warnings for dangling _
  in identifiers.
