Changes in preparation for the release of SolveSpace under the GPL, to add that license, and change all copyright notices to me, not Useful Subset, LLC. [git-p4: depot-paths = "//depot/solvespace/": change = 2211]

Add a screen to edit the view parameters; scale, translation, rotation. Also clean up the handling of units, by putting the conversion factors in only one place, and clean up the expression-parsing but removing all the copies of the same error message.

Replace NameStr with std::string. This removes the arbitrary 64 byte restriction (which effectively limits us to as little as 16 Unicode characters with CJK encodings), makes classes smaller, and is easier to use. As a consequence of making the length of all ex-NameStr fields unbounded, all functions that returned a buffer derived from those were changed to return std::string. Then, functions that are contextually similar to the ones described above were changed to return std::string. Then, functions that now happened to mostly take an std::string argument converted to a C string were changed to accept std::string. This has produced a bit of churn, but is probably for the better.

Use C99 integer types and C++ boolean types/values This change comprehensively replaces the use of Microsoft-standard integer and boolean types with their C99/C++ standard equivalents, as the latter is more appropriate for a cross-platform application. With matter-of-course exceptions in the Win32-specific code, the types/values have been converted as follows: QWORD --> uint64_t SQWORD --> int64_t DWORD --> uint32_t SDWORD --> int32_t WORD --> uint16_t SWORD --> int16_t BYTE --> uint8_t BOOL --> bool TRUE --> true FALSE --> false The following related changes are also included: * Added C99 integer type definitions for Windows, as stdint.h is not available prior to Visual Studio 2010 * Changed types of some variables in the SolveSpace class from 'int' to 'bool', as they actually represent boolean settings * Implemented new Cnf{Freeze,Thaw}Bool() functions to support boolean variables in the Registry * Cnf{Freeze,Thaw}DWORD() are now Cnf{Freeze,Thaw}Int() * TtfFont::Get{WORD,DWORD}() are now TtfFont::Get{USHORT,ULONG}() (names inspired by the OpenType spec) * RGB colors are packed into an integer of type uint32_t (nee DWORD), but in a few places, these were represented by an int; these have been corrected to uint32_t

Added const qualifiers to edit-control string handling FLTK's Fl_Input widget, instantiated as {Graphics,Text}EditControl, returns a 'const char *' string. In order to handle this properly, several of SolveSpace's internal routines needed to gain a "const" qualifier on the edit-control string argument.
