Provides for storing Folder Settings in the central Preferences
Storage as a back-up to the settings stored on each folder. In this
way, even if the LocalStore DB is recreated or otherwise lost, Folder
Settings can be recovered.
1) Does not change the methodology used to read settings while
running, nor the changes in r3107 & r3116 which tremendously improve
Accounts list loading time.
2) Loads Folder Settings from Preferences and stores on the folder
only when creating a new LocalFolder
3) Saves Folder Settings to Preferences and the DB row every time the
Folder Settings are changed.
4) When upgrading from DB version 41 to 42 or later, copies all
settings for existing folders from the DB storage to the Preferences
Storage.
5) Transactional bulk folder creation and single pass local folder
existence check during "Refresh folders" operation drastically reduces
time spent when refreshing folders from the remote store.
6) Uses prepared statement during Editor commit to reduce Preference
storing time.
Probably needs a reversion of r3239, but I'm unfamiliar with
translations, so am leaving that to others' discretion.

Added more comments to explain how the locking mecanism works for LocalStore
Fixed wrong method being called during experimental provider initialization (since provider isn't enabled, that didn't harm)
Add more comments about how the various StorageProviders work and how they're enabled

French localization for storage related settings
Remove unused SD card strings (replaced with storage indirection)

Reset mail service on storage mount (even if no account uses the storage, to be improved)

Migraion -> Migration
move the Storage location preference into preferences rather than the wizard.
Made LocalStore log less verbose Added @Override compile checks
Added ACTION_SHUTDOWN broadcast receiver to properly initiate shutdown sequence (not yet implemented) and cancel any scheduled Intent
Be more consistent about which SQLiteDatabase variable is used (from instance variable to argument variable) to make code more refactoring-friendly (class is already big, code extraction should be easier if not referencing the instance variable).
Added transaction timing logging
Factorised storage lock/transaction handling code for regular operations.
Use DB transactions to batch modifications (makes code more robust / could improve performances)
Merge mail-on-sd branch from trunk
Update issue 888 Added DB close on unmount / DB open on mount
Update issue 888 Back to account list when underlying storage not available/unmounting in MessageView / MessageList
