DDTTYLogger: Favour XcodeColors environment variable
Allow prevention of log file reuse. This is nice if you want to create a new log file at every app launch.
Modification keeps backwards compatibility with existing code as it will maintain previous behavior if the reuseExistingLogFile property isn’t set.

Update DDASLLogger.m
Merge pull request #240 from yonglam/master

Update DDASLLogger.m
Create ASL capture module. It's not yet integrated with the rest of the Lumberjack framework as it's not yet clear the best way to do so.
Changes based on Ernesto's feedback:
* Add new init method too DDLogMessage which takes in a timestamp
* Make DDLog queueLogMessage:asynchronously: public
* Add nanoseconds to ASL capture timestamps
* Adjust some logging levels.
* TODO: Need to figure out how to get ddLogLevel into the ASLLogCapture module so it can be passed to the DDLogMessage init method. Perhaps declare it as extern in DDLog.h?
* Make class a static class
* Allow client to specify whether ASL logs get dispatched synchronously or asynchronously
Add CaptureASL Demo and Travis configuration
New [DDLog log:message:] primitive
Rename static variables
