Fix loading and reloading applications with relative paths and not suffixed
Fix loading and reloading applications with relative paths and not suffixed

It seems Qt changed the way it looks for plugins
with relative paths, this commit allows
QPluginLoader to find your application that was
defined as 'src/libMyApp'.

It also fixes the app reloading if you did't
provide the suffix (.so, .dll...).
