Changelog for package capabilities

0.3.1 (2020-03-10)

Updated package.xml to format 3 and and used condition dependencies to support Python3 (#91)
Contributors: William Woodall

Bump CMake version to avoid CMP0048 warning (#89)
Fixed bug by pruning spec files by black/white lists #84 from commaster90/fix-1 This ensures GetCapabilitySpecs service returns the filtered specs.
Removed a faulty start_capability test. Can't rely on timing of calling stop_capability and then start_capability in quick succession, so this test can't be made to work reliably.
Updated discovery unit test.
Fixed typos in start_capabilities server.
Added test for restarting capabilities.
Export architecture_independent flag in package.xml
Changed to return an error if requested capability is already running. The start_capability service now returns an error code if it cannot start a capability because it is already running.
