latex.lang: revert two commits

Revert "latex.lang: fix bug for environment name (non greedy)"
This reverts commit c83d75c0214faf161966e9440211c3331bbcbd2e.

Revert "latex.lang: add style for name of class, package and environment"
This reverts commit 8536d1be1424889a11a229cbfa5c93b38b58beb4.

The two commits were related, since the bug fix was for the first one.

Reasons include:
- The goal of a *.lang file in GtkSourceView is not to make a file as
  colorful as possible. Adding different colors than normal text there
  don't add much value to me.
  It can even be misleading to add color when it's wrong (the syntax
  would be good, but only with context we would know that it's wrong,
  and doing a full context analysis is beyond the scope of a *.lang
  file, after all it's not a full compiler).

- def:text didn't exist (and it's also a hint that this should be normal
  text, i.e. not highlighted).

The latex class-name, pkg-name and env-name are not used by any standard
style scheme files, so everything should be good from the GSV point of
view.
