new commands:
ApexTestWithCoverage
ApexTestCoverageToggle
ApexTestCoverageHideAll
explain usage of optional connection control parameters
:ApexRemoveStaged now supports tooling jar
several win/unix path handling fixes
documentation update
turns out :sign command does not always support '*' when used with specific file/bugger
documentation update
take into account that we now have two commands with 'ApexTest' prefix

no need to mark file as "coverage sign displayed" when coverage is not available
