v1.7.2

Fixes and minor improvements

Xml:

(technically the first two are breaking changes but are also fixes and arguably break few if any people)

• C-escape control characters instead of XML encoding them (which requires XML 1.1)
• Revert XML output to XML 1.0
• Can provide stylesheet references by extending the XML reporter
• Added description and tags attribites to XML Reporter
• Tags are closed and the stream flushed more eagerly to avoid stdout interpolation

Other:

• REQUIRE_THROWS_AS now catches exception by const& and reports expected type
• In SECTIONs the file/ line is now of the SECTION. not the TEST_CASE
• Added std:: qualification to some functions from C stdlib
• Removed use of RTTI (dynamic_cast) that had crept back in
• Silenced a few more warnings in different circumstances
• Travis improvements
