dbhub: Add context menu actions to all tree views

This adds context menus and some context menu actions to all the tree
views in the Remote dock. No new features are added. This just adds a
new way to trigger existing features but also establishes a place for
future actions for new features.

First you need an identity:&lt;/p&gt;&lt;ol style=&quot;margin-top: 0px; margin-bottom: 0px; margin-left: 0px; margin-right: 0px; -qt-list-indent: 1;&quot;&gt;&lt;li style=&quot; margin-top:12px; margin-bottom:0px; margin-left:0px; margin-right:0px; -qt-block-indent:0; text-indent:0px;&quot;&gt;Login to the dbhub.io website (use your GitHub credentials or whatever you want)&lt;/li&gt;&lt;li style=&quot; margin-top:0px; margin-bottom:0px; margin-left:0px; margin-right:0px; -qt-block-indent:0; text-indent:0px;&quot;&gt;Click the button to &amp;quot;Generate client certificate&amp;quot; (that's your identity). That'll give you a certificate file (save it to your local disk).&lt;/li&gt;&lt;li style=&quot; margin-top:0px; margin-bottom:12px; margin-left:0px; margin-right:0px; -qt-block-indent:0; text-indent:0px;&quot;&gt;Go to the Remote tab in DB Browser for SQLite Preferences. Click the button to add a new certificate to DB Browser for SQLite and choose the just downloaded certificate file.&lt;/li&gt;&lt;/ol&gt;&lt;p&gt;Now the Remote panel shows your identity and you can add remote databases.&lt;/p&gt;&lt;/body&gt;&lt;/html&gt;</string>
