Oembed for slideshare not working anymore
CopyUmbracoFilesToWebRoot assumes packages loacation

CopyUmbracoFilesToWebRoot assumes packages folder is always one dir up from
project file which is not always the case.

I have changed to use MSBuildThisFileDirectory which makes the path
relative the the UmbracoCms.targets file.
MSBuildThisFileDirectory is supported from MSBuild 4 but as ToolsVersion is
already set to 4.0 that should not be a problem.

UmbracoVersion property is no longer required but removing it may break
external target files depending on it. Have moved it to props file as this
makes it more reliable for external targets files.

Bump version
Centralized the current Umbraco version number in UmbracoVersion.txt that will be read by

buildbelle.bat, build.bat and the umbraco.web.ui.csproj so it works in VS, command line and
also in TeamCity.
UmbracoVersion property no longer needed. Added data folder to the targets.
