Numerous fixes for IncompleteCholesky. Still have to make it fully exploit the sparse structure of the L factor, and improve robustness to illconditionned problems.

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)

Index refactoring: StorageIndex must be used for storage only (and locally when it make sense). In all other cases use the global Index type.

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.
