Title:
  Correct dependency checking of plugins

  New

Bug description:
  Wintermute uses a means of package detection (via QPackageKit) and
  dependency checking (similar to find_package of CMake) to ensure that
  the plugin's dependencies are installed (not necessarily properly).
  Wintermute needs to pull this information and use to provide an
  efficient means of ensuring plugin preload stability. The following
  needs to be reached:

  1) Definition of package and plugins compatability. A sample of the
  such (and perhaps a working implementation) is defined here:
  https://github.com/wntr/plugins/blob/master/marytts-
  wintermute/spec.in#L16

  2) Means of obtaining this information. A setup of it (a simple one at
  that) is listed here:
  https://github.com/wntr/core/blob/master/src/plugins.cpp#L203 but can
  be improved on.

  3) Means of validating plugin and package existance. A setup of it is
  listed here:
  https://github.com/wntr/core/blob/master/src/plugins.cpp#L211 but can
  be heavily improved on.

  For points 2 & 3, it may be needed to add two new methods to handle
  packages (i.e: loadPackages(), hasPackages(). Also, a semantic change
  of the methods from loadPackages() and hasPackages() should be
  loadPackages() [of which returns a list of package dependency
  strings], obtainPackages() [of which determines if packages are
  installed in the system with an optional parameter to install if not
  found], and hasPackages() [of which determines if all of the packages
  are installed on the system].

  The same should be done for plugins, whereas the installation process
  should see if it's possible to download them (but that's not a
  priority).
