Add copy/paste xml patch to/from clipboard alongside load/save

[elanhickler]

Looking through the code it seems like the code needs a bit of refactoring, for example, creating a function just to get the xml string, then using that function inside load and then we can use that function inside a "patch to clipboard" function. I'd like to make it easy for users to share patches. I tried to implement this myself but there's so many layers to the load/save system it's difficult to add functionality.

I tried to implement it myself but for some reason #include <juce_gui_basics/juce_gui_basics.h> gives an error in clap-base-class.h, tried a handful of things to solve this, no luck. This is where the needed juce::SystemClipboard functionality comes in.

Yeah you can’t couple to juce there and especially not to juce gui

the editor class can implement copy to clipboard and then the bass class could implement xml as string is probably the pattern you want

would you use ui communication bundle and to/from UiQ?
