[C#] Add ToString

[MFrpurdy]

#852

• Added ToString generation methods.
• In testing these changes user rca22 discovered that data types without encodings - for raw data - were not working correctly. The ToString would not work and the newly added Get/Set to/from String methods would also not work. Fixed.

Example:

[Car](sbeTemplateId=1|sbeSchemaId=1|sbeSchemaVersion=0|sbeBlockLength=45):SerialNumber=1234|ModelYear=2013|Available=T|Code=A|SomeNumbers=[0,1,2,3]|VehicleCode=abcdef|Extras={SportsPack, CruiseControl}|DiscountedModel=C|Engine=(Capacity=2000|NumCylinders=4|MaxRpm=9000|ManufacturerCode=123|Fuel=Petrol|Efficiency=35|BoosterEnabled=T|Booster=(BoostType=NITROUS|HorsePower=200))|FuelFigures=[(Speed=30|Mpg=35.9|UsageDescription='Urban Cycle'),(Speed=55|Mpg=49|UsageDescription='Combined Cycle'),(Speed=75|Mpg=40|UsageDescription='Highway Cycle')]|PerformanceFigures=[(OctaneRating=95|Acceleration=[(Mph=30|Seconds=4),(Mph=60|Seconds=7.5),(Mph=100|Seconds=12.2)]),(OctaneRating=99|Acceleration=[(Mph=30|Seconds=3.8),(Mph=60|Seconds=7.1),(Mph=100|Seconds=11.8)])]|Manufacturer='Honda'|Model='Civic VTi'|ActivationCode='abcdef'

Blocks without braces is not good practice and easy to introduce bugs with.

Done. I also saw an small indenting issue which I fixed.

Looks good. If you fix the generated code to always put code blocks in curly brackets then I'll merge.
