[TIMOB-7368] Tooling: titanium.py create does not add platform tiapp.xml tags as expected

When 'titanium.py create' is run from the command line, the created project does not contain platform tag information in tiapp.xml file, as would be expected. Note: When the new project is imported into studio, the tags are added based on the presence of the platform-specific Resources sub-folder (i.e., Project/Resources/android). This seems unexpected, but this is how it works as of now. Steps to Reproduce: 1. Run 'titanium.py create' from the terminal using the following arguments:

dhydeMBPLion:~ dhyde$ /Users/dhyde/Library/Application\ Support/Titanium/mobilesdk/osx/1.8.1.v20120123161633/titanium.py create --platform=iphone --type=project --dir=/Users/dhyde/Downloads --name=TagTest --id=com.appcelerator.tagtest

2. Inspect tiapp.xml in the new project folder. Expected Result: Deployment target tags would be present.

<deployment-targets>
        <target device="mobileweb">true</target>
        <target device="iphone">true</target>
        <target device="ipad">true</target>
        <target device="android">true</target>
        <target device="blackberry">false</target>
</deployment-targets>

Actual Result: No deployment targets exist.
