automatically remove and prevent installation of apps with a require version less than the current one. We check now the first ad second part of the version number.

Also increase the require tags of the core apps to 4.9 Please note that 4.9 is the internal versionnumber of the upcoming 4.5 release.
You have to pu a <require>4.9</require> into the info.xml of your app to make it as compatible with 4.5
