Sourcing the configuration does not work with tmux 2.6

I tried to use this repo, but all I get is bunch of "unknown command" errors.

@HappyCerberus Thank you for your feedback!
Sorry the description for manually installation in README is wrong. You should just run the script directly since it is a pure script.
I will fix the description later, please keep this issue open.

@HappyCerberus Fixed in 3e8a3a6. Replace the source-file into run-shell should fix the problem.
