Add ofGetVersionMajor(), ofGetVersionMinor()

They return OF_VERSION and OF_VERSION_MINOR respectively
ofNode::setParent and clearParent have flags to maintain global transform

if you change parent of a node (e.g. clear the parent, or give it a
parent), the node's world transformation would snap to a new position.
This is understandable because all of a sudden the node's local
transformation is relative to a new matrix. Sometimes however, the
desired behaviour is that the node stays where it is in the world,
while it's place in the heirarchy changes. This is very simple to
implement. The ofNode::setParent and clearParent methods now have a
flag (default set to false for backwards compatibilty) to do exactly
this.
FreeImage.h Patch for iOS / OSX

Fix for FreeImage error when compiling on OSX for iOS (Xcode)

Problem:
"error: typedef redefinition with different types ('signed char' vs
'int32_t' (aka 'int'))
typedef signed char BOOL; "

Solution:
Use #define and #undef instead of typedef for the type definitions.

Updated for the new version of FreeType and to support the new 64bit
data structures with the define/undef.
Based on the changes @ofTheo made 3 years ago to the same file
