Add missing newlines at end of some echo's (issue #207)

Whilst doing that, i noticed that there were some missing
targets to "make help" so added those in and re-ordered
and re-worded some of the targets to make more sense
e.g. all of the upload's are together, all of the
assemblers are together etc.
