Fix blocks: cap, qui, noi, if, else, else if

What I'm considering doing is:

• creating cap, qui, and noi blocks in the Pygments lexer.
• Entering one of these blocks would stop interactivity until you closed the block. So no code would be sent to Stata until you exited it.
• Sending a block to Stata, even a nested block, I.e. qui { \n cap { \n di "a" \n } \n }, doesn't seem like it would provide two newlines and a dot until the next prompt, so it should run correctly, and then just remove any lines in the output that pexpect captured that have the same text as the input lines. Hopefully none of the output lines will exactly match an input line.

Also do the same thing for if, else, else if

I think for all blocks I can just add {, } to the lexer. Then I can send all lines of a block at a time. And if the last token isn't Text, it isn't ready to send to Stata yet. That seems pretty simple.

The only other thing to watch out for if the code is complete is program?
