Merge the refactoring-branch into master

[marcjansen]

(This is a replacement for #43)

I think we should merge the refactoring-branch into master.

Changes in this branch (which is the cleaned up counterpart of the original refactoring-branch):

• Update to Apache commons-lang3 (mostly used for the model methods toString, hashCode & equals)
• DatabaseDAO
  • enhance getDataByFilter
  • support for fields and ignoreFields
  • support for dotted filters
  • dynamically control the fetch mode (setEagerFetchModeForCollections)
  • add initializeDeep to avoid failed to lazily initialize - no session or session was closed
  • add hasUserRoleByUsernameAndRolename
  • various minor / cosmetic changes
• Filters
  • add support for NotLike
• Requests
  • support for fields and ignoreFields
  • support for dotted filters
• Models
  • BaseModel & friends
  • implement generic hashCode() (subclasses override this)
  • implement generic equals(Object obj) (subclasses override this)
  • implement generic toString (subclasses override this)
  • add info()
  • collections as properties of models
  • most use FetchType.LAZY
  • are fetched using the most performant FetchMode (often SUBSELECT)
  • some are now being serialize in a lean way
  • Group
  • available rolenames now live here as constants
  • new field roles
  • new field deletable
  • MapConfig
  • new field resolutions
  • new field scales

Hi Marc,

thanks for this large PR. I reviewed the commits and in principle everything looks fine, but it seems that https://github.com/marcjansen/shogun/commit/9f3833683b4ea4551fb82e37a079788a41daa83c is part of a project-specific solution. So I would suggest to remove that commit from the PR as it is not really needed in SHOGun.

Regards, Nils
