Remove implicit "set format" from text formatting commands

[chilimangoes]

As suggested by @seekM on the Gitter channel, it's counter-intuitive and not very useful to implicitly set the format mode any time one of the explicit formatting commands ("Gerrish gum bow", "snake bow", "tie bow", etc) is used. Instead, it's more often the case that a user will want to call "set format" with a format that is used heavily through out their code and then use explicit formatting command to handle exceptions.

For example, if I'm working on a public interface in C#, the class and member names would all use "tie gum bow" and the modifiers/keywords/etc would all be "laws bow." Rather than explicity saying the format I want for each, or having to call "set format" to switch back and forth between the two formats, I instead want to say the following:

• set format tie gum bow to set Pascal case as the primary format I want to use
• laws bow public interface ace format my class which would output public interface MyClass
• laws bow string ace format some property which would output string SomeProperty
• etc...

(Obviously, there are simpler ways to write the above code with IDE templates, specialized language commands in Caster, etc)
