Cleanup redundant cl dependency, :group & :require

Browse Source 
* yasnippet.el: Replace calls to cl functions with cl- prefixed cl-lib
equivalents.  Use #' to quote function symbols.
(yas-snippet-dirs, yas-new-snippet-default, yas-prompt-functions):
(yas-indent-line, yas-also-auto-indent-first-line):
(yas-snippet-revival, yas-triggers-in-field):
(yas-fallback-behavior, yas-choose-keys-first, yas-choose-tables-first):
(yas-use-menu, yas-trigger-symbol, yas-wrap-around-region):
(yas-good-grace, yas-visit-from-menu, yas-expand-only-for-last-commands):
(yas-field-highlight-face, yas--field-debug-face): Remove redundant
:group.
(yas-snippet-dirs, yas-global-mode): Remove :require.  The :set value
for yas-snippet-dirs checks if yas-reload-all is fbound, and the
autoload cookie on yas-global-mode makes :require redundant.
