Previously, File::readString used a C-style string as an intermediate buffer via the String += operator. This treats a NUL byte as a terminator, making this function work incorrectly if the File contains binary data. This commit switches the function to use String::concat, which doesn't treat NUL bytes any differently (and is a bit faster, because it doesn't need to use strlen).
