stripsplashes doesn't work if the slash is the only character -> creating file in root dir leads to "//filename"

check if element really exists before calling it. (e.g. for public shared files view, elements like "navigation" doesn't exist)

don´t show negative numbers. this is only a quickfix. I still dont get why the Shared folder can be bigger than the root folder. Perhaps a inconsitency in the filecache?

we are sharing the same file again if item_source of the already shared file and the newly shared file is the same. Therefore we can use the same target name

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

fix create folder and upload file issue on win, fixes oc-1747, solution follows suggestion from bug tracker

We can't rely on the assumption that if the matching target is from the same owner that the share type will be different.
Files in different folders can have the same name. Therefore also a unique name has to be generated if the matching
target it from the same user. Also for folders and files with the same name a unique target name has to be generated

If matching target is from the same owner, use the same target. The share type will be different so this isn't the sa

we can end up with  different items in the shared directory with the same name (Also folder names can contain dots)
