LineDemo class doesn't read input correctly

[interjay]

LineDemo class tries to execute its input letter-by-letter instead of line-by-line.

In demo.py in LineDemo.reload, the line that says:

src_b = [l for l in self.fobj.readline() if l.strip()]

should say:

src_b = [l for l in self.fobj.readlines() if l.strip()]

Additionally, it seems like self.src will not be set correctly since it rereads the file without returning the file pointer to the beginning first. However, this doesn't matter as this member doesn't seem to do anything.
