Enhance bulk-adding solutions to a group

[Herdo]

The folder picker is not the best choice to add solutions as bulk to an existing group. Most likely, you already have a path at hand that you'd just want to paste somewhere and add the solutions beneath this path. The current folder picker however requires you to navigate to the directory again, which is unnecessary in the use-case above.

Change request:

• Allow adding solutions by browsing (as it is now)
• Allow adding solutions by pasting a path from the clipboard

@v-kravets FYI.

@Herdo yes, that's exactly what was looking for, however still would like to suggest use Open Folder dialog from pull request with all other features(like tree navigation, traversing through "focused folders only"(that is chunk of folder hierarchy on currently selected level) using double clicking, search folders using wildcard pattern, etc) if possible - to cover use cases not already reported.

@v-kravets Will be in the next release.
