Integrate Catch reporting with Ceedling

[pJunger]

Two possibilities:

• Either write a unity-like reporter for Catch
• Or replace the unity-parser with a catch specific one.

Using the second possibility nested sections might be better supported?

Ok, second option:

• [x] Generate XML report from Catch
• [x] Parse XML report
• [x] Fill in statistics in Ceedling results
• [x] Fill in detailed results
• [x] Make compatible with stdout_pretty_tests_report
• [x] Make compatible with all reporting plugins
