Build metadata is truncated

[Gama11]

Something seems to be broken in the parsing logic:

trace(("4.0.0-rc.5+4a745347f" : Version)); // 4.0.0-rc.5+4

I think it comes down to parseIdentifier() assuming that something like Std.parseInt("4a") produces null, when in reality it returns 4:

In decimal mode, parsing continues until an invalid character is detected, in which case the result up to that point is returned.
