add g:syntastic_mode_map option

Browse Source 
This option will allow users to fine tune when automatic syntax checking
is done.

The option should be set to something like:

let g:syntastic_mode_map = { 'mode': 'active',
                           \ 'active_filetypes': [],
                           \ 'passive_filetypes': ['puppet'] }

g:syntastic_mode_map['mode'] can take one of 2 values - "active" or
"passive". When set to active, syntastic does automatic checking as
usual. When set to "passive" syntastic only checks when the user calls
:SyntasticCheck.

The exceptions to these rules are defined in "active_filetypes"
"passive_filetypes". In passive mode, automatic checks are still done
for all filetypes in the "active_filetypes" array. In active mode,
automatic checks are not done for any filetypes in the
"passive_filetypes" array.
