* Refactored makefile

Fixed min-js error; renamed routines inline with make conventions

Previously min-js would continually append to the file with `@echo "// @source https://github.com/pomf/pomf/tree/master/static/js" >> ./dist/pomf.min.js`.  Fixed so that it overwrites the file whenever it is run now.

mkdirs was renamed to installdirs as per makefile conwentions
copy was renamed to install for the same reasons

Added clean rule

Removed install from default target

Added DESTDIR,uninstall support

Added dist support

Replaced static program paths; misc improvements

Added missing installdirs target to default target

Added npm_dependencies target

Properly separated "build" and install targets

Modified readme to reflect make install and DESTDIR

Modified .travis.yml to reflect make npm_dependencies

Reverted to cp for install target, temporarily

Ideally this target would use install, but need to work out how to do that properly,  For the meantime, cp works.

Added missing * to install target

Update .travis.yml

Fixed bad markdown

* Update Makefile

* Removed @s cuz ???
