Add Makefile for build and install of org.so

[schoettl]

Hi, cool project. How about a Makefile to build and install org.so? This would simplify the installation section in the README a bit and only recompile if sources have changed...

Thanks for the PR! I'm not sure that I want to include make install to explicitly install to the nvim parser directory.

I'm considering just grabbing the generic makefile from the tree-sitter-go repo. While that wouldn't install to a location that nvim users care about (as far as I know), it does construct a libtree-sitter-org.so.1.0 which could be linked to. It also constructs a c library/header file to include in lower level stuff, which is very cool. I could include an install for nvim specific target in the makefile. Thoughts?

I've already started to revisit the install section, because you're right it's not really very clear. I hope my comment on your issue helps with the nvim install.

The tree-sitter-go Makefile looks clean, too. If it's not overkill given the current state, use that. I understand that the install section is critical. You could of course leave it out.

I will try to install this tree-sitter the next days. I just set up a new ~/.config/nvim config; Now I should be able to use vim and neovim in parallel with different configs.
