v.1.4.0: Gauge fix + small optimisations

• Fixed behaviour of Gauge with positive numbers: the previous behaviour was the same as GaugeDelta (FGauge already had the correct behaviour)
• Added more tests
• Small optimisation: replace string formatting with concatenation (thanks to @agnivade)

v.1.3.0

• Added stdout client ("echo" service for debugging)
• Fixed issue #23: GaugeDelta event Stats() should not send an absolute value of 0
• Fixed FGauge's collation in the buffered client to only preserve the last value in the batch (it mistakenly had the same implementation of FGaugeDelta's collation)
• Fixed FGaugeDelta with negative value not to send a 0 value first (it mistakenly had the same implementation of FGauge)
• Added many tests
• Added compile-time checks that the default events implement the Event interface
