Platform version check during wgt installation - fixed

Platform version check during wgt installation - fixed

m_quiet stays with true value. To get popups run installation
from "my files" menu (e.g. move wgt file to /opt/usr/media/Downloads).

[Issue#] LINUXNGWAP-537
[Feature] Platform version is checked and compared
to required_version from config.xml. If installation
is triggered by pkgmgr, popup with question is shown.
If it is console installation, version check popup is disabled and
installation automatically refused if version not match
[Cause] Compatibility check during installation
needed
[Solution] N/A

[Verification] Build installer. Try to install
widget manual_tests/Tizen_Spec/TC6 from wrt-extra
from console and by pgkmgr (click wgt file from "MyFiles").
