QByteArray: add compare() with case sensitivity options

Need to do the same for startsWith() and endsWith(). indexOf() is a lot
harder.

[ChangeLog][QtCore][QByteArray] Added compare(), which takes
Qt::CaseSensitivity as one of the parameters. This function is more
efficient than using toLower() or toUpper() and then comparing.
