Quad-Lock Unit Converter

* Added ability to perform coordinate transformations from latitude/longitude to UTM (and vice-versa). * Added Heat Flux conversion category with 25 units * Added Magnetic Flux conversion category with 14 units * Added Volumetric Heat Generation category with 11 units * Added 6 new units to Fuel Consumption category (non-linear conversions such as Liters/100km to Miles/Gallon) * Corrected conversion factor in Amount of Substance; 1 mol = 1000 mmol, showed 1000000 mmol * Re-organized main menu. Also, added an icon next to each menu item. * Quad-Lock Converter now uses Unicode for the entire program (UI controls and the engine), enabling internationalization. * Removed restrictions such that users can now add an un-limited number of custom units and categories. Furthermore, users can also add non-multiplicative unit conversions (such as from Liters/100km to Miles/Gallon) * Changed location of UnitConverter.ini (preferences file) to the %APPDATA%\UnitConverter folder or, if running from a removable drive, to the removable drive’s root folder (e.g. F:\UnitConverter.ini). * User defined custom categories can now be rendered visible or invisible in the main window using Main Menu > Edit > Preferences * The conversion engine now uses a hash table to efficiently map unit names to associated conversion factors. This should improve speed on old and obsolete computers (the difference may not be noticeable on fast modern computers).
