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.

Meta: Claim copyright for files created by me This changes copyright holder to myself for the source code files that I've created or have (almost) completely rewritten. Not included are the files that were significantly changed by others even though it was me who originally created them (think HtmlView), or the many other files I've contributed code to.

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 *

LibDraw: Introduce an Emoji class This class can locate and load emojis, which are expected to be stored as regular PNG images at /res/emoji/U+XXXX.png, where XXXX is the character codepoint. https://github.com/SerenityOS/serenity/issues/490

AK: Rename <AK/AKString.h> to <AK/String.h> This was a workaround to be able to build on case-insensitive file systems where it might get confused about <string.h> vs <String.h>. Let's just not support building that way, so String.h can have an objectively nicer name. :^)

Meta+LibC through LibHTTP: Make clang-format-10 clean Why break at LibHTTP? Because "Meta+Libraries" would be insanely large, and breaking between LibHTTP and LibJS makes the commits roughly evenly large.
