• Add MeterPerMinute Speed units (@tongbong)

Fix missing generated code due to merging multiple PRs

• Add nano/micro/milli prefixes to Degree unit (@tongbong)
• Add prefixes nano through kilo to NewtonPerSecond (@tongbong)
• Add Angle units DegreePerSecond with prefixes (@tongbong)
• Add nullable constructor methods (@eriove)
• Add prefixes to LitersPerMinute, fix abbreviations (@rdelhommer)

• Add 3 DynamicViscosity units (@gsokoll)

• Add cubicmicrometer unit (@tongbong)

Add 4 prefixes to Pascal Pressure unit (@schulz3000)
Add 5 prefixes to Bar Pressure unit (@schulz3000)
Add MillimeterPerSecond Speed unit (@tongbong)
Add 16 SpecificWeight units (@bijan86)
Add 9 Density units (@bijan86)
Add 12 Pressure units (@bijan86)
Add TonneForce Force unit (@bijan86)
Add KilogramForceCentimeter Torque unit (@bijan86)

Breaking changes:

• Torque: Rename Newtonmeter to NewtonMeter
• Torque: Change "Nm" abbreviation to "N·m"
• Force: Rename PoundForces to PoundsForce

• Add speed units (km/h, m/s, ft/s, knots, mph).
• Add mass units (microgram, nanogram).

Fixed bugs in Flow and RotationalSpeed units after refactoring to T4 templates (thanks George Zhuikov).
Added Temperature units.

Added missing localization to units for US English and Russian cultures (thanks George Zhuikov).
Added RotationalSpeed and Flow unit classes (thanks George Zhuikov).
Added mils and microinches length units (thanks Georgios).
Refactored to generate unit classes with T4 templates, a lot less work to add new units.
