Unfortunately, the svn repo is a bit out of date. This commit contains 8

changes that haven't made it to svn. The descriptions of each change are listed
below.

- Fixes some python shebang lines.

- Add ElementsAreArray overloads to gmock. ElementsAreArray now makes a copy of
  its input elements before the conversion to a Matcher. ElementsAreArray can
  now take a vector as input. ElementsAreArray can now take an iterator pair as
  input.

- Templatize MatchAndExplain to allow independent string types for the matcher
  and matchee. I also templatized the ConstCharPointer version of
  MatchAndExplain to avoid calls with "char*" from using the new templated
  MatchAndExplain.

- Fixes the bug where the constructor of the return type of ElementsAre() saves
  a reference instead of a copy of the arguments.

- Extends ElementsAre() to accept arrays whose sizes aren't known.

- Switches gTest's internal FilePath class from testing::internal::String to
  std::string. testing::internal::String was introduced when gTest couldn't
  depend on std::string.  It's now deprecated.

- Switches gTest & gMock from using testing::internal::String objects to
  std::string. Some static methods of String are still in use.  We may be able
  to remove some but not all of them.  In particular, String::Format() should
  eventually be removed as it truncates the result at 4096 characters, often
  causing problems.
