Turn on --adjustdirection in mafft to orient sequences

Previously, sequence orientation occurred from lastz matches and
orientation was stored in the sqlite database.  However, with smaller
probe sequences, orientation values can sometimes become confused.  The
better option is to have mafft orient strands prior to alignment, which
was not an option earlier.  Add --adjust direction to mafft string.
alter trimming code to correctly place missing data characters at ends of alignments where there are gaps
allow removal of _R_ designator added by mafft during strand orientation as part of locus name
adjust addition of missing data designators for MultipleSeqAlign and _R_ strand indicator added by mafft
add code to get many fasta lengths and output as CSV
update code for slight change to alignment object
