* std.uni: use dstring for upper/lower/title tables
* std.uni: make tables use dstring
* Add space after cast for Dscanner
* Remove redundant semicolons
This avoids parsing large files reducing parse time by 30 ms for me
(it took ~70ms to parse tables, now ~40ms).
And move hangul sets to Trie tables as well.
Also saves around 30Kb on "hello world" app.
