FMSLogo Code

Fix the test to pass integers to SETACTIVEAREA, now that SETACTIVEAREA throws an error when given non-integral numbers.

Fix the example for :ERRACT to match how FMSLogo behaves.

Fix an unnecessary warning when running IFTEST by replacing a call to IF with IFELSE. The call was intended to act like IFELSE, but was not testing the IF-becomes-IFELSE behavior.

Fix an off-by-one bug that prevent cnv_node_to_intnode() from returning an int node when the number was FIXNUM_MAX.

Fix a memory corruption bug in ranged_integer_arg that was introduced during some recent refactoring.

Add missing #include to fix build breaks when not compiling with a precompiled header.

Add additional test variations for parsing numbers.

Fix bug #338; SETACTIVEAREA now throw errors when given non-integer values.

This required a little refactoring of the argument and conversion logic to provide an "integer only" argument checker.

This revision also includes a regression test that SETACTIVEAREA persists the new settings to the configuration.

Add function comments to numberp()

Add a function to uninitialize the DLL subsystem. This cleans up memory which a Logo programmer may have forgotten. It also fixes an assert failure in the case when DLLFREE is not called.
