Remove transaction type

Browse Source 
This basically started with this change :

 /* Transaction */
 struct __pmtrans_t {
-       pmtranstype_t type;
        pmtransflag_t flags;
        pmtransstate_t state;
-       alpm_list_t *packages;      /* list of (pmpkg_t *) */
+       alpm_list_t *add;      /* list of (pmpkg_t *) */
+       alpm_list_t *remove;      /* list of (pmpkg_t *) */

And then I have to modify all the code accordingly.
