Header path fix
Add methods which handle prompts for a DBus object path

 * Various prompting methods return the prompt result as
   a GVariant.
 * Added new prompt_path methods to SecretService
Add secret_service_read_alias() and secret_service_set_alias()

 * Wrappers for Secret Service ReadAlias() and SetAlias() methods
   in various permutations.
Add methods to get services from collections, items

 * Add secret_collection_get_service()
 * Add secret_item_get_service()
Release version 0.3
Added Polish translation
build: Fix srcdir != builddir
secret-tool: Don't read uninitialized variable on error path
Add SECRET_SCHEMA_NOTE

 * A real simple schema for stuff stored by the user.
 * No attributes
Don't leak extra mock service when running python tests

 * Were erroneously starting the mock service when loading
   the python test modules, although already started in setUp()
Pass service GType to secret_service_new() and friends.

 * This allows callers to use a custom SecretService derived
   type with the rest of libsecret
 * The default way to get a SecretService is via secret_service_get()
   which remains simple without the GType parameter
Notify the 'items' and 'collections' properties when udpated

 * When SecretCollection updates its 'items' property or
   SecretService 'collections' property notify that these
   have been changed.
Use correct variant signatures for Secret Service signals

 * Fix typo for signatures used when receiving CollectionCreated,
   CollectionChanged, CollectionDeleted, ItemCreated, ItemChanged,
   ItemDeleted
Fix null-pointer dereference

 * In the corner case where we don't know about a collection/item
   but receive the CollectionChanged or ItemChanged signal,
   fix use of a null pointer
Update the collection 'Items' property correctly

 * Problems due to not setting constructing flag when construction
   of SecretCollection completed
Proper async behavior for seahorse_collection_delete ()

 * The async 'source' object was set to a SecretService
   instead of a SecretCollection in the callback
Don't dispose SecretItem proxies when they go away

 * This is strange behavior and causes unexpected results
   in calling programs
Call correct method for secret_service_unlock()

 * Previously erroneously called "Lock" instead of "Unlock"
Use correct path when initializing a collection
Use the correct 'g-properties-changed' signal
