Description
Now that pinyin parser is working better we should work towards replacing the plugin for pinyin input in the typed answer field (probably after each word rather than per line, done with color too). I mean the one that is used when you have specific to type in answers. The current plugin is very buggy and ignores keystrokes (not that I use it much but I guess I might use it more if it worked better)
At the same time we should make it work better for Chinesee pinyin. In particular we should make it report errors in text verses tones separately. Currently, if you wrote "ni4 hao4" then the first i and the a would be marked wrong. In reality they are right but the tone is wrong.
This could be corrected by providing two line feedback, i.e. bottom line does letters and ignores incorrect tones, top line only considers the tones (using numbers) and rest is ignored.
