Reworking comments
Comments on main page more-or-less works. It's a bit slower than before. Comments on piece pages still throw an error because the DC number is a string.
Cosmetic revisions in profile, piece, comment views
Comments: link to "person" page from username
Fixed: types of data in comment handling code
Fixed: added parameters to timeout calls
Changed where updatePieceComments gets its parameters
Improved: Manual refreshing not necessary, because of timeout.
Fixed: collecting data from a POST query in comment submission
Revised: Show comments accordion even if no comments yet
Fixed: No pagination needed in single-page scrolling canvas view
Revised: refactored analysis/piece script to avoid redundant code
Fixed: Clear (but don't reset) comment textarea after submission
