Make neocomplete a little bit less crazy
Several changes in vim and tmux

First I removed the configuration to start counting from 1 from the tmux
config file because I like to have my irssi window on 0.

For vim I've made several changes.

- Added swedish so it is recognized when checking spelling.
- The Silver Searcher (ag) is used for :grep if it's available.
- Google search for the keyword under the cursor with <leader>g
Adds the Swedish language files for vim
