    readme: simplify install procedure
    
    The README is inside the tarball, so by the time someone reads the
    README, the tarball is already extracted. Besides, if someone wants to
    compile GtkSourceView from source, we can expect that extracting the
    tarball is something that he/she can do.
    
    ./configure && make && make install is the standard procedure, no need
    to detail everything.
    
    And replace % by $ as the shell prompt. Bash is usually the shell
    installed by default.
