Merge lp:~rafalcieslak256/ubuntu-accomplishments-daemon/NewAPI into lp:ubuntu-accomplishments-daemon

[Rafał Cieślak]

This branch fully implements the changes for the new API.

It, thus, removes many functions from the API, and adds a lot of new ones, according to specification.
Instead of passing file paths around, the accomIDs are now a basic data form that functions exchange - more details in the spec wiki page.

 * The new API introduces a lot of atomic functions, and rest of code makes use of them whenever it is possible.
 * The self.accDB is used to store all data concerning accomplishments in memory, for easier processing. It's a dictionary, that maps accomIDs to their data. It also stores information about collections (collection name as the key) and sets (key: "collection:set").
 * Pre-loading all data into accDB also reads ABOUT and extrainformation files, to store default lang in memory, for easier further usage (e.g. in get_all_extra_information), which also results in accomplishment collection files being accessed in only one function in code (reload_accom_database)
 * Apart from the new API, this branch also does some clean-up. I removed unnecessary, unused variables, groped common code into single functions (for e.g. displaying bubbles).
 * log.msg calls in __init__ changed to print, because __init__ happens before the logger is ready to work, and thus such messages were never displayed.
 * Caching images is not slightly simplified.
 * self.accomplishments_path got renamed to self.accomplishments_installpaths, as it now should allow to install accomplishments in several places, according to config file. It can store values (paths) separated with a ':' character.
 * "Scripts path" is now abandoned, as it can be in many different places. Instead, accDB stores 'script-path' for each accomplishment.
 * get_extra_information makes use of prepared translated labels.
 * 'author' fields (if present) are loaded and stored in collection data - one can use 'get_collection_authors' for an array of contributors to given collection.
 * The DBus API was accordingly updated.
 * Trophy files now contain an 'id' field, that stores accomplishment ID for the trophy, instead of using separate application and accomplishment fields.

passing empty extra-information in case none is set, for DBus does not know how to send NoneType
