Fixed a few issues discovered in testing on python3 (#260)

* gwsumm.archive: copy table before archiving

so that things aren't broken when we try to use the same table for data processing

* gwsumm.tabs: cast `map` to `list`

so that we can index it with python3

* gwsumm.tabs: fixed broken HTML for SEI tabs
