Visibilities.INHERITED constant added (occurs only during resolve), changed after overridden descriptors resolve
Fake descriptors are created for invisible properties as well (is necessary for better error reporting)

moved files extensions into a Files.kt and added File.forEachLine for easier iterating through a file in lines

- Analyze is reference variant is suitable for completion before creating LookupElement
- Show visibility icon in completion list for kotlin declarations

 #KT-1756 fixed

#KT-1788 Fixed - added standard collection APIs to the various kinds of Array and removed the few old hand-crafted versions of these methods

Remove analyzeProjectWithCache with caching on project. It's used nowhere, gives cycles in resolve and produce second copy of binding context.

changed resolution order: first priority is 'local extensions; members; nonlocal extensions', than by implicit receivers (before was vice versa)

added count(predicate) helper function to String along with Char.is*() methods from java.lang.Character

fixed up apidoc comments and fixed bug in kdoc where macros would not be used if there was whitespace before the @

simplified the test cases for the preconditions and add them to the API docs; also added requireNotNull() and checkNotNull() helper methods for converting nullables to non-nullables easily in code with optional exception messages

#KT-1785 Fixed. adds printStrackTrace(writer|stream) to Throwable so that the intrinsic Throwable behaves more like java.lang.Throwable. (Though not totally sure why we don't just siwzzle Throwable -> java.lang.Throwable like we do for Collection et al)

#KT-537 adds A.to(B) helper method to make easy creation of map literals: hashMap("a" to 3, "b" to 6) etc

refactored the to(Collection) methods to be called toCollection(Collection) to avoid clashing with a potentially new method called to(T) for making a pair/tuple/Map.Entry

added some missing sortedSet() methods and kept simpler naming convention of (sorted|Linked)(Map|Set)() for functions to create linked/sorted map/set
