Intuitive way for user to set the Filename Encoding

[ak19]

Max came up with a very nice way to help users to work out which filename encoding may be suited to their files.

• Rightclick on an *individual* file and it will show a list of the following, but only for each encoding supported by the JVM:

"ENCODING NAME: filename as it appears when encoded"

This way the user can see if the filename looks good in an encoding and then use that encoding name to apply to *multiple* selected files.

• If an encoding is required that is not supported by the JVM, they can still specify this as the value for the "gs.Filename Encoding" metadata field in the Enrich tab. This will always store it as metadata with the filename, even if a particular encoding that's not supported by the current JVM can't therefore be applied for the filename *display* in GLI.
