Updated Entity Framework package to v5 (v4.4 for .Net 4) for VS2012
support of update-database command.
Upgraded EntityFramework from 4.3 to 5.0 to fix issue with VS2012 and  EF migraation utility. EF5 doesn't build DB correctly for domain classes that have multiple inheritance levels (WorkerSignin and ActiivtySignin). Added explicit Identity option to DB build in EntityTypeConfiguration object for the table.
Updated WorkOrder/View.cshtml to restore larger font for printing of assignments on workorder view
Removed English Level 4 from Lookups.cs
Cleaned up 2 compiler warnings (property defined but never users)
Refactored Lookups in MVC layer. Replaced all Lookups calls that provided drop-down lists.
Removed unnecessary LookupGroup and LookupSkill classes. They only provided easy property navigation in the cshtml files, but added complexity that made filtering on inactive skills more work.
Changed automated tests from Firefox to Chrome. Faster and more reliable IMHO. Requires chromedriver.exe path to be configured in Machete.Test\app.config
Added LType enum; simpler method for selecting a lookup with intellisense support.
removed unnecessary ToList() call, added comment
Renamed LookupCache.getBySkillID to LookupCache.getByID
