develop branch - bug importing TsConfig

[kszymukowicz]

On develop branch there is bug on importing TsConfig.
File ext_localconf.php

Wrong

       $pageTs = '@import \'FILE:EXT:' . $extensionName . '/Configuration/TsConfig/Page/All.tsconfig\'';

Should be

        $pageTs = '@import \'EXT:' . $extensionName . '/Configuration/TsConfig/Page/All.tsconfig\'';
