Updated where leader key is set and made var in lv-settings (#474)

- Setting leader-key in the init.lua file. You want to set the leader as
  soon as possible so that it's the same everywhere. With the leader
  being set in the lua/lv-which-key/init.lua it resulted in mappings that
  used `<leader>` in the lua/keymappings.lua mapping the the defualt
  leader-key of `\`
- Added the O.leader_key to the lv-settings.lua file so the leader-key
  can be set there, which seems to make more sense.
- Added handling for when the leader-key is `<Space>`. This could be
  made more robust to include other special keys, but I don't think
  many/any of the other special keys would be used as a leader-key (ie
  <BS>, <CR>, <Tab>, <Esc>, <Up|Down|Right|Left>, etc.)
