[gtksourceview/wip/latex] latex.lang: better command highlighting

    latex.lang: better command highlighting
    Highlight the name and the option.
    Currently the common-commands have a higher priority, so for example
    won't work, since \usepackage is in the common commands. A solution is
    to transform the common-commands into a regex, and have two command
    contexts: one for common commands, and one for other commands.
