Some bugs of code_mobject.py

[TonyCrane]

Here is some bugs of #1036

Bug 1. For Text()

The front spaces are not in front of the first character, but in the front of all of the characters, like this:

text1 = Text("  ab\ncd", font="Consolas", size=2)

So it will look not good when TransformText:

text2 = Text("ef\ngh", font="Consolas", size=2)
self.play(Transform(text1, text2))

Bug 2. For Code()

Background color of codes is choosed by html file pygments made, so if I let style='vim', the background color of codes will be the same as the background color of Scene.

And if I let style='autumn, the background color would be the same as the color of line numbers:

These are the 2 bugs I have found so far.
code_mobject.py is a good idea, but it ’s too early to submit pull requests and merge.
@NavpreetDevpuri Hope that you can fix these bugs.

I'm poor in English, hope you can understand me :)
