Consistency in parameter names: algo vs algorithm vs method

[szhorvat]

At this moment, some functions use algorithm as a parameter names (e.g. shortest_paths, sample_pa, etc.), some others use algo (e.g. page_rank, feedback_arc_set, etc.), and yet others use method (e.g. sample_degseq, sample_tree, etc.). The naming should be made consistent across functions.
