Implemented some features

[npanuhin]

Implemented some features from #4310:

• Remove redundant keys that specify the general default value, notably platforms (also "platforms": ["windows", "linux", "osx"]) | Done for platforms
• Translate labels to lower case | Currently commented, because it only shows an error, but does not change the value (maybe this is okay?)

Also, changed redundant keys:

• "osx-x32" and "osx-x64" -> "osx"
• "linux-x32" and "linux-x64" -> "linux"
• "windows-x32" and "windows-x64" -> "windows"
