in zcl-loader-dotdot.js:

	* making sure discriminator ref is set correctly for all strings

	* making sure is_signed is set correctly for all numbers

	* dealing with subatomics (by processing them last)

	* picking up atomic size from length property

fixing incorrect value in zcl-loader-consecutive.test.js and adding string count test in zcl-loader.test.js
