#4 Allow ebuilder properties to be specified directly

[Mirko Raner]

Currently, ebuilder obtains all build properties from the build properties file specified by the "-build" parameter. Most of the time, the properties file only contains very little information, and it may be desirable to get rid of that file completely. To address this, ebuilder should also be able to read the build properties from the VM's system properties. An example for the command line usage could be:

eclipse -data workspace -build -vmargs -DimportWorkspace=.. -updateSiteDestination=updates
