add WMS 1.0.0 parser
Rename ol.projection.getFromCode to ol.projection.get
Allow strings to be used wherever projections are needed
Use strings rather than ol.projection.get in examples
Round image height and width for WMS
Rename projection functions for a friendlier API

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.
