Try to use seek, but it's a little bit confused now and added slim filetype.
Cannot find the usefulness of seek and vim-panel. Updated some indentation settings.
Added Java chords.
Added vim-rspec and tsilme.vim bundles. Also added new mappings for run rspec and set slime key mappings.
Added 3 new mappings that send custom_command, `clear` and  to tmux.

Run custom command silently is better.
