Upgrade script for BASE 2.17 --> 3.0

[Nicklas Nordborg]

The existing BASE 2.17 database should remain mainly intact, but there may be some things that we need to move around to different tables. We don't know any details yet but we'll probably need some kind of script for this. Here is a list of what we have found so far:

• Remove the affy_chip column from the ArrayDesigns table. This column has not been used for a very long time (BASE 2.5?)
• Remove the jar_path column from the 'PluginDefinitions table. But first copy the filename (not path) to the jar_file` column.
• Remove the jar_path column from the JobAgentSettings table.
• Remove references to jarPath property from context filters, sort settings, etc. for PLUGINDEFINITION.

Removed almost everything from Update.java since we will only support upgrading from BASE 2.17.
