Allow syntax checking to happen on buffer change

Browse source 
Add a variable `syntax-checking-check-on-buffer-change` to the
`syntax-checking` layer which conditionally sets the variable
`flycheck-check-syntax-automatically` to:

 - `'(save mode-enabled)` when nil
 - `'(save idle-change new-line mode-enabled)` (the package default)
   when non-nil

The various settings determine when Flycheck evaluates the buffer:

 - `save` triggers a buffer check after buffer save.
 - `mode-enabled` triggers a buffer check when `flycheck-mode` is
   enabled.
 - `idle-change` triggers a buffer check after the editor has been idle
   for `flycheck-idle-change-delay`
 - `new-line` triggers a buffer check whenever a new line is inserted
   into the buffer
