[milestone/11.7.2] Version 11.8 (#89)

* - Browser Session Class: add AWBrowser to simplify configuration for AirWatch browser

* - no longer output "computed: '<null>'" entries for class settings in the LogIntro if it is the only entry for that MDM parameter

* - OCAuthenticationMethodOAuth2: use UUIDString instead of UUID description for lock name
- OCCore+FileProvider: add handling for edge case when the database is not available or not open, preventing a hang
- OCCore+ItemList: implement coordinated scan for changes
	- synchronizes scans for changes across processes
	- prioritizes scans, giving the app highest and the fileprovider second highest priority
	- consolidate related log messages under ScanChanges tag (including PollForChanges and UpdateScan)
- OCLock: add support for trying to acquire a lock and immediately returning with the result, with a new OCErrorLockInvalidated error code in case the lock couldn't be acquired
- OCDatabase: add .isOpened property
- OCSQLiteDB: disable statement caching in minimum memory configuration

* - change "refresh_token" to "refresh token" in English Localizable.strings.

* - OCLocale: modular localization system replacing direct system localization calls
	- OCLocaleFilter: layers that strings run through during localization to allow transformations
		- ClassSettings: allows overriding individual strings with replacements provided through a dictionary from class settings
		- Variables
			- allows replacing {{variables}} with values, or dynamic content from "variable sources"
			- shared instance allows addition of sources and changing variables at runtime
			- provides generally useful variables like app.name
- change OCLocalized() set of macros to call OCLocale, not NSLocalizedString/NSBundle directly

* - OCLocale:
	- fix bug when replacing placeholders with sources
	- add support for passing additional variables via options (+ OCLocalizedFormat macro)

* - OCLocaleFilterVariables: add missing "{{" and "}}" in search term for replacements

* - OCCapabilities: add support for dav > propfind > depth_infinity capability

* - OCItemPolicyProcessorVacuum: fix wrong metadata type for OCClassSettingsKeyItemPolicyVacuumSyncAnchorTTL (bool -> integer)

* - Add CHANGELOG for 11.8 release
