    Fixed some corner cases in the log find functionality

    When logging output the cursor defaults to the end of the document.  This made the search method hit the end of the document before ever trying any searches.  When doing OutputGUI().log(..) we now reset the cursor to the beginning of the document.

    Add a syntax highlighter for the log window

    * Generalized the syntax highlighting logic into a GenericSyntaxHighlighter class.

    * Refactored the DiffSyntaxHighlighter to use the new generic highlighter as a base class.

    * Added a new LogSyntaxHighlighter which is also based on GenericSyntaxHighlighter.
