Falkon has no KDE integration on kubuntu cosmic

[Sergio Callegari]

Launching falkon on kubuntu cosmic causes it to start with the following complaint:

Plugin "KDEFrameworksIntegration.so" not found
Invalid plugin spec of "lib:KDEFrameworksIntegration.so" plugin

Because the KDE integration plugin is not present in the deb and likely not built at all in the packaging of Falkon. As a consequence, falkon knows nothing of the KDE KIO mechanism. This mean that the value of falkon on the KDE desktop is significantly hindered, not being usable as an alternative for the venerable konqueror.

This is certainly a packaging issue, since the Falkon author confirms that the KDE Frameworks plugin is currently maintained in falkon, but some of the build requirements may have changed recently.
