shenleban tongying 540dda26ed cleanup: Replace all usages of qrcx://localhost with qrc:// 
The replacement command:
git grep -l 'qrcx://localhost' | xargs sed -i 's/qrcx:\/\/localhost/qrc:\/\//g'

The qrcx:// URL scheme was introduced in 2009 or earlier - it is present
in the first commit in GoldenDict's git history. Back then GoldenDict
supported Qt versions earlier than 4.6, in which
QWebSecurityOrigin::addLocalScheme() was introduced. Adding the qrc URL
scheme as local obsoletes the qrcx URL scheme. GoldenDict does not
compile against Qt versions earlier than 4.6, so there is no reason to
use this custom URL scheme anymore.
