Fix pixel alignment and draw2DLine inconsistent offset problems. New test added to make sure that drawPixel and draw2DLine use the same alignment.

- Restored the ability to set a textures by a float interface, but this solution was marked as deprecated.

This is done to allow all tests running through even when one has a problem. Otherwise people just comment-out the asserts. The macro will log file, line and assert-test to the tests.log.

Added setName and getName to IGUIElement, the same way as it's in ISceneNode. Note: I don't yet add a function like ISceneManager::getSceneNodeFromName to IGUIEnvironment as well. The reason is that current implementations of related functions ISceneManager::getSceneNodeFromId and IGUIElement::getElementFromId are done very different and I first have to figure out if there's any way to reconcile those sanely.

irr::s64 now compiles with -ansi and -pendentic on gcc without warnings. Also can now be disabled completely by define.

- line2d::getLength now returning type T. f64 would actually be fine, but then it has to be used throughout, here the cast to T happens before already, so returning f64 is just confusing as looks like it would return a greater accuracy than it has at that point.

Add irr::s64 back in (using long long for non VS compilers). If there's any problem with this please inform me, I'd like that to stay in as it makes Irrlicht a lot easier to use in combination with the Clipper library (a boost-licensed library for working with 2d polygons).

- line2d::getClosestPoint can now also get the closest point on the line additional to only checking for closest point on the line-segment.
- Avoid division by zero in line2d::getClosestPoint when start- and endpoint are identical.

Last change to xml-reader (returning whitespace as well) was maybe correct, but wrecked too much code expecting old behavior. So now instead there are no EXN_TEXT nodes returned which only contain whitespace, which should also work cross-platform and is closer to the old behavior. We can make that flag public later on, but should probably first fix the mess with getNodeName and getNodeData returning the exact same value.

Fix for render context change where only the window id is given. We now try to change only the window ID, keeping context and display unchanged. Suggestion by vovo4ka from the forum.
