Fix many long to int conversion warnings:
...
- fix usage of Index (API) versus StorageIndex (when multiple indexes are stored)
- use StorageIndex(val) when the input has already been check
- use internal::convert_index<StorageIndex>(val) when val is potentially unsafe (directly comes from user input)

bug #897 : makes iterative sparse solvers use a Ref<SparseMatrix> instead of a SparseMatrix pointer. This fixes usage of iterative solvers with a Map<SparseMatrix>.

bug #877 , bug #572 : Introduce a global Index typedef. Rename Sparse*::Index to StorageIndex, make Dense*::StorageIndex an alias to DenseIndex. Overall this commit gets rid of all Index conversion warnings.

Do not apply the preconditioner before starting the iterations as this might destroy a very good initial guess.
