Fix _cmd_proxy()

[Moosems]

@rdbende This isn't quite working. Could you work on this while I eat dinner?

I figured out what's wrong. It's inserting the text first and then I'm trying to figure out where in the heck the inserted text is.

[Moosems]

I think I got it working. We should do some extensive tests to find any possible issue that could occur from this as its a pretty big change. If it works properly then this fixes #21.

@Moosems Please find those "most outlandish issues". I haven't tested this with .replace for example, but I guess it will break.

[Moosems]

Delete breaks (started working on a fix) but I haven't yet dove into replace a bunch.

@rdbende I don't know what in the world was changed but inserting is now broken. The insert part was actually pretty good so I would've stuck with that.

Code that breaks it:

from chlorophyll import CodeView
from tkinter import Tk

root = Tk()
cd = CodeView(root)
cd.pack()
cd.insert("end", "\"\"\"This is a test\n")
root.mainloop()

from chlorophyll import CodeView
from tkinter import Tk

root = Tk()
cd = CodeView(root)
cd.pack()
cd.replace("1.0", "end", "print('Hello, World!')")
root.mainloop()

@Moosems I simplified the code, because there was some unnecessary hacking-around with indexes, and the delete was completely broken. Now it mostly works. Feel free to add more changes, I won't be able to work on this today.

[Moosems]

Test (works):

from chlorophyll import CodeView
from tkinter import Tk

root = Tk()
cd = CodeView(root)
cd.pack()
cd.insert("end", "\"\"\"\nThis is a test\n\n\n\n\"\"\"")
cd.insert("end", "\n\nprint()")
root.mainloop()

Typing doesn't highlight until you go to a new line (press return)

[Moosems]

highlight_area() highlights everything one char to the left:

Traceback (most recent call last):

Looks good to me.
