Refactor Log File (continued)

[Kittyfisto]

Fixes #200

Reason for this change

ILogFile continues to have properties (as in C# properties) which shouldn't be modeled as such and instead be an ILogFIlePropertyDescriptor:

• Not every aggregating / proxy ILogFile implementation needs to care about a myriad of properties to be forwarded
• It's possible for different log file implementations to offer different sets of properties
• Custom log files may bring their own properties and have them displayed to the user for free

Any expected problems concerning backwards compatibility of existing plugins?

Yes - Any plugin implementing ILogFile

Changed Types

• Removed ILogFile.MaxCharactersPerLine and replaced it with TextLogFileProperties.MaxCharactersInLine
• Removed ILogFile.EndOfSourceReached - It was only used for tests and never should have been part of the public interface to begin with
• Removed ILogFile.Count and replaced with with LogFileProperties.LogEntryCount
• Renamed ILogFile.GetValue to GetProperty along with its overloaded extension methods
• Renamed ILogFile.GetAllValues to GetAllProperties

Any expected problems concerning backwards compatibility of existing user settings?

No

Does this break existing user workflows?

No
