tablesorter: add latest version 2.16.2; remove 2.15.14 no longer needed; extra dev-master version of tablesorter was causing errors so removed it.

[ENH]Work started to reduce the amount of text shown by default for each profile in the Profiles Wizard and provide screenshots for each one of them. To be continued (missing many screenshots still). Icons associated with profiles might be fully removed in a later commit to simplify UI (just hidden in html comments in this commit, as a starting point to let others see the visual change).
