Bugfix and smarter output file updates

Fixes bug with schemas not ending in a newline.

Adds feature that avoids touching output files that already exist and have identical content to what would be written. This can reduce recompilation when updating schemas.

Fix bugs regarding empty namespaces and conflicting wrapper names

This release fixes a couple of problems related to generating invalid code when cross referencing types in the empty namespace.

Additionally, starting with this release, it will generate code for boxed fixed decimal types by default. You can suppress this behaviour by specifying the --use-long-fixeddec option
