CMake: only write edited file when changes made

Caused cmake to run after every icon update.

Cleanup: typos

WIP: Rename settings function in Draw Manager

Added note about potential crash in add_orco_dm()

Construct new Mesh instead of writing to ob->data

Even when ob->data is a CoW copy, it can still be used by different objects
and thus shouldn't be modified by a modifier.

Merge remote-tracking branch 'origin/master' into blender2.8

Fix string comparison in GNUMakefile for linux systems

CMake: generate icon list for installation

MSVC users weren't getting icons installed, since glob isn't reliable,
list all files in a section which the update script maintains.
