[minor] Local build process updates

[muz]

A handful of minor changes from trying to build things locally;

• The Makefile needs to pass in package otherwise the expected JAR files for the Client and Server are not correctly built, and are then unable to be included in the generated ZIP file
• The Utils/build-and-package.pl script generates and tries to clean up after itself a temp directory. To safeguard the cleanup not working or local dev leaving it around, explicitly ignore it to prevent adding it to the git tree
• The Makefile uses a deploy directory as a target, in the same vein as the second point, exclude it from git

Of course, another option here is to make the Makefile just write to the temp directory like that Perl script does, and then only need to include that in the .gitignore for this workflow
