Server-side improvements

[isc-bsaviano]

• Fixes Bug: server side search misses searching class member definitions #1480
• Report search matches in the ROUTINE header and non-description comments in the class definition.
• Improve conversion of include and exclude glob arrays to regular expressions.
• Create an enum of supported isfs query parameters and a new helper method for getting the isfs display configurations from query parameters in a Uri. This significantly reduces the use of “magic strings”.
• Create new helper method for getting the name of a document from an isfs Uri.
• Create new helper method for creating a fuzzy match string to be used with the SQL LIKE predicate. Currently used to find workspace symbols and files.
• Use new workspace connection picker for project commands.
• Improve source control action picker prompts (see 'Server Source Control' and 'Server Command Menu' flipped after connecting to different server #1458)
• Re-write queries for discovering server-side unit tests to improve performance.
• Always hide .bpl and .dtl files since users can’t edit them.

Looks good based on code-reading. A couple of nits picked. I will install the dev VSIX and see if I spot any problems in daily use.
