Minor cleanup items for ReadTheDocs

02_running_kpp_sample_mech.rst
- Updated some cross-references for better readability
- Trimmed trailing whitespace

04_input_for_kpp.rst
- Updated "target language" from a rst link to a ref

07_numerical_methods.rst
- Changed "Other" section to "Other integration methods"
- Added descriptive text for beuler & feuler
