Ability to specify shader attribute properties fully at runtime. 

There's a new DynamicAttribute class that is very similar to Attribute,
but it has the location and base type as runtime properties instead of
them being a part of template. This allows for more flexibility, but
OTOH also more typing and more responsibility on the user. See
MeshGLTest for details and usage comparison to the Attribute API.

#### Dynamically specified attributes
In some cases, for example when the shader code is fully generated at runtime,
it's not possible to know attribute locations and types at compile time. In
that case, there are overloads of @ref addVertexBuffer() and
@ref addVertexBufferInstanced() that take @ref DynamicAttribute instead of
@ref Attribute typedefs. Adding a RGB attribute at location 3 normalized from
unsigned byte to float with one byte padding at the end could then look like
this:
@code
mesh.addVertexBuffer(colorBuffer, 0, 4, DynamicAttribute{
DynamicAttribute::Kind::GenericNormalized, 3,
DynamicAttribute::Components::Three,
DynamicAttribute::DataType::UnsignedByte});
});
@endcode

Basic workflow is: bind specific framebuffer for drawing (if needed), set up
