STunney/BobArnson: WIXFEAT:4239

Add option to not extract the .msi when melting .wixpdbs. Don't leave temporary cabinet files behind (unless -notidy is in effect).
Reverted unintentional change from bad patch.
Add security to Hidden Burn Variables by calling SecureZeroMemory on the value, encrypting the value, and adding SecureStringVariables to the managed Engine.
WIXBUG:4328 Fix for VSIX Id's having spaces
Make StringVariables use pointers so that the IBootstrapperEngineSecure interface can be deleted.
Consolidate the StrUtil Secure methods so the code isn't duplicated.
Formatting.
Per feedback. Restore Common.DeleteTempFiles and wrap it in AppCommon instead.
