quse: improve per package USE-flag output somewhat

- add asterisk at the end of USE-flag instead of at the start of the
  line to mark currently enabled flag (installed package)
- colour such enabled flags green so they stand out better
- wrap descriptions when they don't fit on the terminal screen

example:

app-portage/portage-utils-0.80_pre20190610
  nls*        Add Native Language Support (using gettext - GNU locale utilities)
  static      !!do not set this during bootstrap!! Causes binaries to be
              statically linked instead of dynamically
  openmp      Build support for the OpenMP (support parallel computing),
              requires >=sys-devel/gcc-4.2 built with USE="openmp"
 +qmanifest*  Build qmanifest applet, this adds additional dependencies for GPG,
              OpenSSL and BLAKE2B hashing
  libressl*   Use dev-libs/libressl instead of dev-libs/openssl when applicable
              (see also the ssl useflag)
