remove download scripts, consolidate into script
most of them were just calling the gitclone script, so remove them. the grub script was treating gnulib as a dependency. i've now added the ability to grab 1 dependency, in the gitclone script (it should be expanded later to support multiple dependencies) the gitclone script has been renamed to "fetch". the "fetch_trees" script does more or less the same thing, but calls "fetch" and handles multiple revisions if a project needs that this is more efficient, and slightly reduces the code size of lbmk!
