New package-info.xml commands for Release 2.1

This is a proposal for adding the ability to use < input > tags in the package-info.xml file.
It gives mod authors the ability to use HTML5 input and textarea for installing or uninstalling their modifications where the data can be processed in files accessed via the < code > tags.

I authorize the use of this additional code for any releases of the SMF software package.
