Notes:
- define local.properties to locate the android sdk
- use 'ant nightbuild' to clean,update and upload the nightbuild
- the ant's svn update works only over readonly copy (some ssl problem with https)
- the ant's ftp upload task needs commons-net.jar from apache on ant's classpath
- building may not work on windows where workspace path has spaces like 'C:\Program Files\' etc...
