Consider proxy objects as 'linked' ones when it comes to ID remapping.

Reason is, on next fileread, proxy will be assigned with its target's data again...
Note that this may not be true about all its datablocks pointers - but proxy objects
are really brittle in current code anyway, they could use a serious work as well.

Moar cleanup, some fixes towards sanier handling of remap & indirect data...

Proxy are still not correctly handled here though.

Relocate library: first working code.

Basics seem to be working, proving idea is valid. There is much to do yet though,
handling correctly all possible scenarii (especially those including indirect libs
used by several libraries, or libs used both directly and indirectly, etc.)
is not going to be a piece of cake...

Serious rework (again) of append/link code, to make it more generic.

Making the code in WM area more generic (will be used by relocate libs feature too in future).
And multi-append/link shall no more close & re-open lib files for each and every idcode!

Also, serious cleanup of BLO_append_... API (renamed BLO_link_..., since it links and never appends!),
main real changes there are removing the bContext arg in favor of scene/v3d (a bit more verbose, but does
not requires a valid context anymore to be able to instanciate ob/groups!). And logic behind instanciating
or not has been simplified, previous code was really obscure and sometimes redondant, from quick tests
it still works as expected.

This is temp branch for until 2.76 is over, shall be merged in master asap then.

Move most of (currently NoP) relocate code to WM area.

More work towards relocate operator for libraries (still pretty much empty shell).

Note that this op will have to be moved to WM area in fact, it's way too generic for Outliner only...
and we need to re-use most of append/link operator code!

Outliner: add a dedicated ID_LI operation handler, and add skeletton for 'relocate' tool...
