Fix T42977: Weights failed to display in Wireframe mode when using Face Select

D948, reviewed by @mont29 (thanks for that)

Fix T43010 regression in material setting.

Caused by own fix for another display case.

Shoud be safe for 2.73 final.

Fix T43013: Flip with bridge aligned loops

OSX: revive GHOST_HACK_getFirstFile cause it breaks things on older OSX versions.
Dunno exactly why this was done earlier, but propose not to remove code not understood.

Fix T42641, Graphical fragments showing on Blender 2.71 and higher when baking.

Safe for 2.73...

This revert rB9b0ab890676790bb1e8e77797629b889ea66f69e - needed to set that threshold to a small
negative value to remove the last artefacts reported in T39735, but now I could not reproduce
any with the previous 0.0f value, so restoring it for the time being.

If this 'shadowed neighbor face' case re-appears, we can always choose a value in-between, like -1e-18f...

Only add a fill brush to default .blend if there isn't one already. For
some reason this happened twice here.

Likely candidate for 2.73 final

Fix rna paint update callbacks assuming meshes

Cycles: Fix really bad bug with shadow rays on non-SSE CPUs

basically shadow rays were totally broken and most of the time did not record
any intersections, leading to really ad rendering artifacts.

This commit makes it so regardless of enabled optimization level render result
would be the same.
