Code for correct aligned display of sequences

Tried to used the grid system offered by Bootstrap model but it didn't
work out as expected. Instead I decided to go off working with the
tables. However, the main problem was splittig up the alignments into
multiple rows and displaying properly. This required a lot of
not-nice-looking code. Morever, taking care of Plus/Minus of the hseq
was another tricky case (which again added a even more code). However,
it is working as in the original version.
