misc: adds customizable options to syntastic Nit syntax checker

g:syntastic_nitc specifies custom path to compiler
g:syntastic_nit_dir specifies the NIT_DIR env variable
g:syntastic_nit_args specifies extra arguments to call nitc
g:syntastic_nit_include_dirs lists directories to include, must be a list
