-Update regex in EasyMotion#WBW ('W' and 'B' movement)

-Update regex in EasyMotion#EW ('E' and 'gE' movement)
- Add global option EasyMotion_maximal_jumpmarks.
 It limits the number of jump targets for the motion. If the search
 goes in both directions, they will be handled separately.
 The option was just added to speed up the automated tests in t/compare_movements_spec.vim.
