Maestro: consider initializing the unmanaged browse to a specific directory if supplied in template

[jbirch]

I have created a custom FeatureSource template for unmanaged SDF files, specifying the following:

 <Parameter>
    <Name>File</Name>
    <Value>%MG_DATA_PATH_ALIAS[unmanaged]%SDF\Engineering\</Value>
  </Parameter>

The SDF GUI editor recognises that this is an unmanaged connection, but when I hit the data source browse ellipsis it starts me at the top of the unmanaged tree. It would be useful if it started out browsing at the directory specified , even if the file itself is invalid.

I could work around this by specifying an existing file, but I prefer not to have to maintain that link.

Fixed with r4466.

The code also keeps track of the last selected folder. If the resource has an unmanaged path, that one is used, otherwise the last selected path is used.
