Allow to use double quotes and slashes in annotation names

Currently annotation names and group names are stored in GenBank files as qualifier values. This behavior cause some issues if the name contains double quotes or slashes. It is need to add a possibility to store these symbols e.g. by escaping them with backslashes.
Note that if GenBank files with qualifiers with these symbols can't be correctly opened by other popular bioinformatics tools, then these symbols should be prohibited in annotation and group names.
