Removed RCS $Id$ string

Each VIC release already has an version ID string that can be accessed
by the user by using the '-v' commandline option.

Developers can use 'git describe' to get detailed information about the
release they are using. The $Id$ was redundant.
Merge branch 'dev5/issue_107' into feature/reorg
