Clipboard support and Locations menu update
I have added support of clipboard: now any input field supports copy (Ctrl-C) and paste (Ctrl-V) hotkeys. So to find a planet which name has been shared on the forum, just copy it from your browser (Ctrl-C) and paste it in the Search-by-name menu (Ctrl-V).
Also I have added buttons "Copy" and "Paste" to the Locations menu. Now, to share your location on the forum, you do not need to open the config. Just click the "Copy" button, and the location's code will be copied to the clipboard; then just paste it into a message on the forum. Conversely, to import a location from the forum, select the location code, copy it to the clipboard (Ctrl-C) and press "Paste" button in the Locations menu.
