Add storagecount method to return number of device storages in use
Add searchcompletecount. filematchcount and searchkey as properties of Applait.Finder
Add reset method to reset internal tracking and storage
Add a generic log method for easy printing of messages to console in debugmode
Separate out filename matching to a separate method called matchname
Use self instead of context
Do reset() when search begins and use searchkey property with casesensitive operation
Use log method and make search complete even more accurate

Now a new event called `storageSearchComplete` is raised when each storage area is completed. The event `searchComplete` is only raised when the entire search is completed.
Make Applait.Finder inherit from EventEmitter. Lesser code. Everyone's happy.
Clean up properties and use lowercase property names
Add property documentation, upgrade version info and make overall docs better
Update README.md with latest docs
