This change removes all changes that were anticipated here for
WMS GetFeatureInfo handling, including the IWMS interface and
the goog.provide for 'ol.tilegrid'. I'll create a separate pull
request for WMS GetFeatureInfo eventually, taking into account
the suggestions from the discussion in #402.
With this change, url functions are called in the scope of the
source they are configured for. This allows us to simplify the
url function generation for WMS, using a more generic
createFromParamsFunction factory, and the source's new params
member.
Note that there is also a new url member for WMS sources. This
is the WMS base url (the first one in case there is an array of
urls for faster tile access). This can be used for accessing
other WMS services (especially GetFeatureInfo).
The following functions are renamed:
getTransform -> getTransformForProjections
getTransformFromCodes -> getTransform
transform -> transformWithProjections
transformWithCodes -> transform
With this change, the faster functions that avoid projection look-up
have longer names and are used internally, whereas the slower but
friendlier short name functions are available for users.
To avoid surprises, we configure everything that is a WMS GetMap
request parameter in the params object, and not as direct
configuration option. This affects the VERSION and TRANSPARENT
params.

This change adds a lot of flexibility to working with tile
layers: Sources where the server projection or tile grid do not
matter can now be constructed without specifying a projection or
tile grid.
The tileUrlFunction/imageUrlFunction now also creates updated
URLs when the params of the layer change, so things like
mergeNewParams in ol2 will be possible.
A nice side effect of this whole change is that there is no more
duplicated code between tiled and single image WMS layers.
While I was at it, I also fixed a WMS 1.1.1 axis order issue
and incorrect STYLES params (STYLES=& instead of STYLES&).
