use SemVer based versioning on chef-server packages

pre-release version tag will be prefixed with a '-' while nightly build
tag (including build times tap and git info) will be prefixed with a 
'+'.

Exclude the stress tests on windows
only set default value for CHEF_GIT_REV if value is unset

This will ensure we don't inadvertently set a value for CHEF_GIT_REV in 
other projects in this repository (i.e. chef-client)! Would be 
preferable to change the 'load the world' project loading logic in 
Omnibus: 
https://github.com/opscode/omnibus-chef/blob/master/Rakefile#L16

We really should only load the project definition for the project we 
want to build.

write out BUILD_VERSION file with version string generated in build

This will ensure the version released to Omnitruck matches alternate
build_version formats (like SemVer).

chef-server-ctl: unset ENV vars that affect Ruby environment
    
Ensure the calling environment (ಠ_ಠ Bundler) does not infect our Ruby

remove unicode characters in comment

That's what I get for being cute.
ensure we don't accidentally release the BUILD_VERSION file

Ruby's Enumerable.find returns the first value for which the block 
evaluates to true. Depending on the sorting order of the local_packages
array this may be the BUILD_VERSION file instead of the desired package
file.
Add stats_hero config to chef_wm for erchef

You can now configure the top-level key used in metrics reporting. The
default is "chefAPI".
