Several changes to improve maintainability, readability and style of
packaging meta-data:
* Use more maintainable syntax in templates. That is, more MKit macros,
line-based lists, etc.
* Use Markdown for LICENSE.
* Use normal case (don't YELL) in application name.
* Use only spaces to align spec file.
* Use version ranges for SemVer dependencies.
* Sort %files section.
* Use shorter version level (0.y vs 0.y.z) in ranges where possible
* Move MKit compatibility directive to bottom (which actually changes
the compatibility level to 0.0.24 as older MKit had a bug that
prevented seeing the directive near the bottom.)
