Remove empty spaces and backslashes for all plugins

[vivekb91]

Reference #63

[CodeCombiner]

As we talk before backslashes should be present, is that correct?

[rampr]

Yes, backslashes should be present for content that has only numbers. Backslashes make them get interpreted as strings instead of number/float.
