Chromatograms in the msa view

Work with chromatograms and alignments at the same time is a routine of Sanger-based sequencing.
Chromatograms must be included under sequences in msa and updates must be synchronized.
See Sequencher(http://genecodes.com/) or SnapGene for more detail.

The request is described in this discussion: http://vk.com/uniprougene?w=wall-74359225_134
