Custom snippets added, surround remapped, easymotion on visual

Just added the folder snippets/ so there can be snippets outsite of
vim-snippets bundle that are carried along with the repo.

Surround now has \{delimiter} instead of <D-{delimiter}>, easier to
strike

Easymotion user <space> and <s-space> for bidirectional jumps to begin
of words or ends, both working with Visual mode
