Change the new window option 'tab' to 'tab_window' so that it is similar
   to all the other options values ('same_window', 'split_window',
   'vsplit_window').
Unified the GetLocation code in function vimside#util#GetLocation.
Unified all new window code in the function vimside#util#GotoSourceLocation(dic).
Added the function vimside#util#GotoExistingSourceLocation(line, file)
   that lets one go to an existing window if the file is already open there.
   This copies some of the code found in VIMRUNTIME/macros/editexisting.vim.
Removed the vimside/swank/evnet debug event handlers.
Added initial debug code - its not tested so I am sure it does not work.
Added sign.vim that allows one to create Vim signs. This unifies the use
    of signs by quickfix window, location window and debugging.
Added locationlist.vim which lets one create window specific location list
   windows.
When checking Vimside versus Ensime Scala versions, Vimside now ignores
  the trailing part of the version numbers when comparing for equality
  (i.e., Scala 2.10.0 now equals 2.10.1 ).
Added a number of Options that allow the user to control if signs are used
  and, if so, how they are displayed:
        'sign-quickfix-error-linehl'
        'sign-quickfix-error-text'
