Meta: Add license header to source files As suggested by Joshua, this commit adds the 2-clause BSD license as a comment block to the top of every source file. For the first pass, I've just added myself for simplicity. I encourage everyone to add themselves as copyright holders of any file they've added or modified in some significant way. If I've added myself in error somewhere, feel free to replace it with the appropriate copyright holder instead. Going forward, all new source files should include a license header.

Everything: Move to SPDX license identifiers in all files. SPDX License Identifiers are a more compact / standardized way of representing file license information. See: https://spdx.dev/resources/use/#identifiers This was done with the `ambr` search and replace tool. ambr --no-parent-ignore --key-from-file --rep-from-file key.txt rep.txt *

SystemMonitor: Move process window to GML Extra stuff done in this commit to facilitate the above (if you want to really push my commit count, ask for more atomicisation): - Register a bunch of widgets that are used in the process window. - Allow setting the pid after the fact for the process state widget.

LibCore: Put all classes in the Core namespace and remove the leading C I've been wanting to do this for a long time. It's time we start being consistent about how this stuff works. The new convention is: - "LibFoo" is a userspace library that provides the "Foo" namespace. That's it :^) This was pretty tedious to convert and I didn't even start on LibGUI yet. But it's coming up next.
