msidb: Add support for exporting database tables. 

msidb allows developers to export tables from a database with the "-e"
mode flag followed by a list of tables.  For example, this call would
export three tables to the current directory:
msidb -d package.msi -f . -e ActionText Component InstallExecuteSequence
