Types highlighting support

[cmpute]

Hope that the type name can be highlighted like in C++. This might be quite different from python highlighting since this requires to detect type names. For example the types in following statement:

cdef <typename> <obj>
cdef cppclass <typename>[<template>]
cdef struct <typename>
def/cdef/cpdef <return type> <function>(<arg type1> <arg name1>, <arg type2> <arg name2>, ...)
