Make RbVmomi a proper Ruby Gem

- add rbvmomi.gemspec to build Gem
- remove Gemfile.lock as it should not be versioned in Gem repository
- add lib/rbvmomi/version.rb so VERSION can be used from library
- remove VERSION as lib/rbvmomi/version.rb replaces it
- modify .gitignore to include and remove necessary files
- move bindir to exe/ so binstubs don't get included
- remove jeweler, rdoc, and rcov from Rakefile
- only use SimpleCov in tests
