Subject: [PATCH] Fix issue #7

Instead of assuming that the default created window in a new session has
a index of `0`, we now check window index for the session with Tmux's
list-windows command.

Additionally, the default window is now moved to index `999` instead of
`99`, cause I'm paranoid and probably stupid :)
