Fix incorrect rendering of tilemaps with csv data on windows

[bolino]

Each tilemap row would be shifted to the right a certain number of tiles.

When saving Tiled maps with data in CSV format it is saved like this:

<data encoding="csv">
7,7,7,7,7,7,7,7,7,7,7,7,7,7,7,7,7,7,
7,7,7,7,7,7,7,7,7,7,7,7,7,7,7,7,7,7,
7,7,7,7,7,7,7,7,7,7,7,7,7,7,7,7,7,7,
7,7,7,7,7,7,7,7,7,7,7,7,7,7,7,7,7,7,
7,7,7,7,7,7,7,7,7,7,7,7,7,7,7,7,7,7,
7,7,7,7,7,7,7,7,7,7,7,7,7,7,7,7,7,7,
7,7,7,7,7,7,7,7,7,7,7,7,7,7,7,7,7,7,
7,7,7,7,7,7,7,7,7,7,7,7,7,7,7,7,7,7,
7,7,7,7,7,7,7,7,7,7,7,7,7,7,7,7,7,7,
7,7,7,7,7,7,7,7,7,7,7,7,7,7,7,7,7,7
</data>

When reading each line there is a carriage return at the beginning which in windows is '\r\n'.
Because of how each line is parsed the '\r' at the beginning of each line would be parsed as a tile id.
On windows we must remove all '\r' from the parsed string.

I had talked about the issue here: https://discuss.cocos2d-x.org/t/cocos2d-x-v4-0-released/48487/106?u=bolin

As i know, cocos2d-x doesn't support .csv format. Why not use .xml format?

That's what I read in the comments of TMXTiledMap but we've been using csv data for months without problems.
Also if you check TMXMapInfo::endElement(void* /*ctx*/, const char *name) you can see both base64 and csv formats are being parsed.

void TMXMapInfo::endElement(void* /*ctx*/, const char *name)

Csv data is easier to read if you want to examine a level file in text editor and also file sizes are a little bit smaller. I'd also say loading csv data is faster but I haven't done any tests. In newer version of Tiled xml data has been deprecated.
