Release 0.4.5

[markb]

Another bugfix release primarily. There are few visible changes, but some significant behind-the-scenes changes. HOPEFULLY no new bugs were introduced, but please be on the lookout.

• Fixed server error when uploading pocket queries containing new countries or new states. DEJA VU, yes, this is another attempt to fix this issue but it is quite a significant change and has a very high likelihood of resolving this issue once and for all.
• API bugfix for logging-in error from native clients (i.e. blackstar) when username has spaces. This may still require changes in native client to complete the fix.
• Add verbage to new user screen indicating requirement for premium groundspeak membership.
• Add warning if pocket query upload is older than 25 days.
• Added links at bottom of cache details page to geocaching.com for cache gallery of images and add cache to watchlist.
