Bug fix for MS Windows - the spin viewer window was being hidden by the main window when switching pipes.

The window is now being re-raised to the front.

Bug fix for racing in the spin viewer window when switching pipes.

The pipe.switch user function was queue rather than synchronously executed, so that the execution
lock would block the switching of analysis tabs if too many spins were present.

Clicking on 'Execute relax' now also shifts the log window of the relax controller to the end.

Clicking on 'Execute relax' now raises the relax controller to the front, if already shown.

Implemented the sys_info user function GUI page and menu entry.

The help-about.png oxygen icon is now available on the help_about path.

Created the front and backend of the sys_info user function.

This displays the same text as 'relax -i'. This will be useful on the Mac OS X app, as the command
line is not available.

The GUI prompt window is now also deactivated with the execution lock.

This will prevent race conditions as previously the user was able to execute any user function or
manipulate any of the data in the relax data store, while execution was in progress!

More of the main menu entries have been disabled with the execution lock to prevent racing.

The spin loader toolbar button in the spin viewer window is now properly disabled with the exec lock.
