ADT Resource Repo stores IDs and Called Once

ADT Resource Repo stores IDs and Called Once

This change makes ADT parse out @+id declarations from layout and
menu files and store them in its ResourceRepository. This eliminates
the need to merge in IDs from the generated R.java in order to have
a complete repository of resources.

In order to do this, a new type of ResourceFile is created:
IdGeneratingResourceFile which is used for xml files in menu/ and layout/.
Also includes an IdResourceParser which finds all the declared IDs in an XML.

This change also includes a change to the ResourceMananger to process
raw deltas that can be provided either from the PreCompilerBuilder or from
the GlobalProjectManager. This is to avoid duplicate deltas being passed
to ResourceManager when autobuilding.
