Crash when trying to open user subreddits (r/u_user) for users with a dash (-) in their username

Please note, the example user here ( u_Ruby_Soho- ) is NSFW, I only encounter this issue with my NSFW account because of how I use Reddit. This particular one also contains underscores ( _ ) but I know from other encounters that those are fine and it's the dash that is the problem.

In order to actually follow a user requires being able to open the user subreddit ( /r/u_username ) for them, but that isn't possible if the username contains a dash/hyphen ( - ) because the app hits an exception. Also tested with latest RedReader alpha version 363. (And earlier)

Here's the report it generated for sending by email, which I've done before, but this is the issue tracker.

Start by tracing the user-subreddit action through LinkHandler and RedditURLParser, focusing on the null RedditURLParser.RedditURL before generateJsonUri() is called. Reproduce the crash with the reported username containing a dash, such as u_Ruby_Soho-, and verify that opening the user subreddit no longer crashes.
