Fixed bugs for crashing while fresh board list and entering a post.

As showed in two modified files.
In CC98Parser.m, I updated these XPath paths and regular expressions when parsing html tags. 
In BoardListTableViewController.m, I added a getting personal board list data statement. Without such a process, the board name showed would be unreadable as it's unicode while the whole page is utf-8. I've asked DJ, he said tech support had no idea about such a case.

PS:
It's some months after the last commit, you must be very busy in Canada, aren't u? 
Maye we can make effort to let this project more popular by some way?;)
