Created a FIFO object for the relax controller log.

This allows for asynchronous writing to sys.stdout and sending this output to the log controller,
preventing the GUI from slowing down calculations by having to wait for the GUI to update.

Key events are now controlled in the relax controller log element.

This prevents text insertion and deletion.

Scrolling now follows the end, if at the end, in the relax controller log window.

Implemented limited scroll back on the LogCtrl relax controller log element.

This will prevent the computer from running out of memory. The maximum number of lines is now
stored in the status singleton.

Started to create a custom control for the relax controller log element.

This is derived from wx.stc.StyledTextCtrl and will allow much greater control.

Mouse text selection is disabled in the relax controller log window.

This is so that the WriteText() call always adds the text to the end, by preventing the insertion
point from changing.

Set the relax controller log window font to the fixed width font modern_8.

Renamed the relax controller IO redirection append_text() method to add_text().

The relax controller is now using the WriteText() method to allow for scrolling back in the logs.

Reverted r14054 as this fix actually broke things.

The command used was:
svn merge -r14054:14053 .
