Unfortunately, the svn repo is a bit out of date.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.
