Improve documentation for upgrade_only #115

From this section: https://github.com/zyedidia/eget#does-eget-keep-track-of-installed-binaries

if so it will only download a new version if the GitHub release is newer than the binary on your file system.

The documentation fails to explain how "newer than" is determined.

its implied this is not by any sort of tracking of eget (no manifest)
based on timestamp?
based on versions?

It's based on timstamp, afaict. That would be the simplest interpretation of 'newer' - and is what the code actually does: https://github.com/zyedidia/eget/blob/master/eget.go#L270

Getting a version without keeping state would mean trying to run <binary> --version and capturing the output, hoping that's safe, etc... which is a whole minefield.
