Freshen Makefile and update README.md

README.md

• Add sudo to revelvant commands
• Use named languages (bash) in fenced codeblocks

Makefile

install target

• Use install with permissions set

The permissions on has were 777 from git clone.

• Add option to use $PREFIX

What if I don't want to install to /usr/local/bin?

make PREFIX=$HOME/.local install now works.

update target

• Add update target for git fetch
• Include .PHONY targets

tests

• Add tests for Makefile changes

• Uses bats variables for directories

• ✓ make install creates a valid installation

• ✓ ..even if has is missing from directory

• ✓ make update runs git fetch

Thanks for the PR. To be able to merge it should pass on Travis CI. Could you please check that?

I am away right now but will certainly take a look at it little later in the week.

It was and still is, passing on my local checkout.

I will add some bats' feedback and commit shortly.

Well. That was a bit more effort than I expected. But I'm ready to start using bats properly now. (with bats-assert-1 thankyou!)

I would have happily merged it today but the make install target is now broken on macos. any suggestions?

Sadly, some long opts dont work on macOS. had to change them to short flags :(
also cp -u is also not available. so had to remove it. :(

We can work on those in future commits. Didn't want you to fix them, so committed changes to master. you can review them if that works for you on your setup.
