libsmartcols: add scols_cell_get_alignment()

Just to hide that we use cell flags (bitwise operations) to define
cell content alignment. The patch also more explicitly specifies the
flags in the header file.

The alignment is evaluated in the order: right, center, left. The
default is left.

Note that SCOLS_CELL_FL_* are used for for table title only.
