Type parametrised test cases

[JoeyGrajciar]

Description

This PR adds the support, docs and some unit tests for type parametrised test cases. Currently there is support for up to 8 types for these test cases.

Introduces TEMPLATE_TEST_CASE and TEMPLATE_TEST_CASE_METHOD macros. Usage of these macros is very similar to TEST_CASE and TEST_CASE_METHOD. Difference is that name and description (even empty string) is required as types for test are specified at the end. Example:

TEMPLATE_TEST_CASE("Templated test","",int,float, std::string)
{
    std::vector<TestType> v( 5 );
    REQUIRE( v.size() == 5 );
    REQUIRE( v.capacity() >= 5 );
}

template<typename T>
struct TemplateFixture
{
    TemplateFixture() : m_a( 1 ) {}

    int m_a;
}

TEMPLATE_TEST_CASE_METHOD(TemplateFixture,
    "A TEMPLATE_TEST_CASE_METHOD based test run that fails", 
    "[.][class][template][failing]", int, float, double)
{
        REQUIRE( TemplateFixture<TestType>::m_a == 2 );
}

@myrgy actually working on v2.0 of this without cap for types :) hold on currently doing some local tests of implementation :)
