Other changes include:
* utils: utilsGenerateFormattedSizeString() now takes an input double instead of size_t.
* DownloadTask: calculated speed is now expressed in bytes per second, so now it's up to the caller to convert it to other units.
* DownloadTask: set download size and percentage if the download size isn't known and we're dealing with the final chunk.
* http: slightly improved CURL error info formatting.
* OptionsTab: fully implemented NSWDB XML update option.
Other changes include:
* Updated borealis.
* Updated Makefile.

* OptionsTab: added a small disclaimer about dump options.
* OptionsTab: added notifications for the update application item (running as NSO, app already updated).
* config: improved boundary handling while validating integer entries.
* utils: (de)initialize CURL (this will be moved to http.c eventually).
