BibIndex: use human friendly index name

* Adds a more administrator friendly progress display when
  running a BibIndex task in BibSched as it prints the index name
  in addition to the more cryptic index tablename.
  (addresses #1329)

* The same progress display now also tries to give an estimate
  of completed work in percentage.

WebSearch: tweaks SPIRES two-digit search

* Instead of having a window ending at the current year
  e.g. for 2012: 1913 -> 2012
  the new two-digit year window is 10 years ahead:
  e.g. for 2012: 1923 -> 2022
  This permits to search for near future dates.
