Bogdan Poplauschi 1b618e8d35 Merged framework targets + using xcconfig
- Xcode 10 (already supported)
- merged the framework targets into multi-platform ones
- using xcconfig for most of the configurations (Lumberjack.xcodeproj + Tests.xcodeproj + Demos) - only adding setting in xcodeproj where they are not valid for all the other targets
- set deployment target to iOS8 and Mac OS 10.10 - also cleaned up some branched code for the earlier versions
- updated Travis scripts

### Use Log Level per Logger
If you need a different log level for every logger (i.e. if you have a custom logger like Crashlytics logger that should not log Info or Debug info), you can easily achieve this using the `DDLog.add(_, with:)` method in Swift, or `[DDLog addLogger:withLevel:]` method in Objective C.
#### Swift
```swift
DDLog.add(DDOSLogger.sharedInstance, with: DDLogLevel.info)
DDLog.add(DDFileLogger.sharedInstance, with: DDLogLevel.debug)
```
#### Objective C
```objc
[DDLog addLogger:[DDOSLogger sharedInstance] withLevel:DDLogLevelInfo];
[DDLog addLogger:[DDFileLogger sharedInstance] withLevel:DDLogLevelDebug];
```
You can still use the old method `+addLogger:`, this one uses the `DDLogLevelVerbose` as default, so no log is excluded.
You can retrieve the list of every logger and level associated to DDLog via the `[DDLog allLoggersWithLevel]` method.
