Doesn't handle splat's new string comments, raising ValueError

[2Tie]

In a recent version of splat, decoded strings add a block comment in the following line containing the original hex of the string, like so:

    /* 25B9A8 0035B828 */ .asciz "砂漠岩地"
    /* 8D BB 94 99 8A E2 92 6E 00 000000 */

currently, mwccgap doesn't handle lines with just a block comment, raising the ValueError in preprocessor.py.

my stopgap fix was to add the following lines before the raise ValueError line:

                if re.sub(r'/\*.*?\*/', '', line).strip() == "":
                    #ignore comment-only lines, i.e. after strings
                    continue

this snippet checks if there's only whitespace in a line after removing the block comment.
