Shogun Post command line options

Shogun Post supports the following command line options:

Option	Description
`--force-gles`	Load in Graphics Compatibility mode, which forces Qt to use OpenGL ES. This may help to work around graphics driver issues.
`--SkipSplash`	Do not show the splash screen.
`--crash-handler arg`	Optionally, specify `quiet` or `system`. If used with no argument, the Vicon crash handler is used.
`--exit-after-script`	Close Shogun Post after running the init script.

Example usage:

> C:\Program Files\Vicon\ShogunPost1.14\ShogunPost.exe --SkipSplash
