FontManager: fixed trace mode
app_server: workaround for GCC 4.7 misbehavior in IntRect.

* moved the inlined BRect constructor of IntRect to the cpp file. GCC will inline the method
anyway.
* impacted methods were both AGGTextRenderer::RenderString() in
src/servers/app/drawing/Painter/AGGTextRenderer.cpp, calling the StringRenderer constructor
with a BRect reference.
* unless someone comes up with an explanation, I'll try to come with a smaller testcase to
submit this problem upstream.
