screen and vim builds dependences

[nestorlafon]

Specific building options or versions are need for most of the vim configuration or colors, it would be good to have at least the list of dependences somewhere

Any vim above version 7 should work.

I guess I could add a test that disables the whole thing if vim is below 7. That would work for the settings in my vimrc, but some of the plug-ins would still fail when you run an older vim.

I'll start by documenting the requirements in the README file.

/vim 7.0 was released in July 2006. 6 years later, it should be everywhere. I'm closing this because I've moved on from places that don't have the right tools :P
