JAL-1645 JAL-1701 fix up split frame docs and add a bit more info about reconstructed alignments. maybe we need a screenshot here too.

+  <p><strong>Reconstructed Alignments</strong>
+    Reconstructed alignments are typically <em>not</em>
+    the same as the alignment produced by aligning the complement
+    sequence set directly with the external service. However, in the
+    case of protein alignments, a reconstructed cDNA alignment is often
+    more reliable than one calculated without coding information.
+    Reconstructed cDNA alignments are also more informative than the
+    original protein alignment when calculating phylogenetic trees or
+    performing other kinds of molecular evolution analysis.
