Hotfix for "missing docker dependency" issue when installing specter with pip.

Binaries

There are two types of binaries in this release:

• specter_desktop - a windowed GUI application with Specter server included
• specterd - a command-line program that only runs Specter server

Note for MacOS: If Specter-Desktop app appears in the tray, but doesn't start the server, go to Applications, find the app, right-click on it and select "Open" - it should solve the problem once and for all, so next time you should be able to launch it as normal.
