In future, if a dev edits the second arg and miscalulates the corresponding 3rd arg, there will be a buffer overflow or the string (2nd arg) will be cut short. This commit prevents that.

The parser assumes all lines end in newlines, but sometimes this isn't
true. Check for a null terminator along with '\n' when stripping leading
spaces.

* parser: Fail gracefully if a nonexistent file is passed on the command line

Before, if a nonexistent file was passed to LoadFileText(), it would
return NULL, and the parser would happily dereference it.

* parser: Refactor Makefile and update the path to easings.h (now reasings.h)

Before, the `make all` target would simply segfault, see 0a679d79
Now, if a file in the `make all` target doesn't exist, make will write
an error.

Individual API files can be generated likeso, provided the header file
the target depends on exists:

FORMAT=JSON EXTENSION=json make raygui_api.json

In order for the `make all` target to succeed, raygui.h, physac.h and
rmem.h need to be added to the correct directory.
