Multi-line sequence view

Description: In context of primer selection/cloning a biologist works with one sequence in a moment, so it is good to show more nucleotides of a sequence by breaking it by lines.
Scope:
Develop a multi-line sequence view. The following requirements must be taken into account:
-multi-line sequence view works only for one-sequence visualization. Multi-line view of multiple sequences is restricted
-multi-line view is shown in the Details View area.
-multi-line view is good for printing. If all translations, complementary sequence, overviews, etc. are switched off it must look like a sequence with a ruler and spaces between line.
