#165- Right, Ctrl+Right key behaviour

http://www.intellij.net/tracker/netprofiler/viewSCR?publicId=165
When user presses right it should do the following: if current node isif current node has children it should move to its first child. If it doesn't it should move to its next sibling. If the node doesn't have sibling it should move to deepest available sibling of one of node's ancestors.

Ctrl+Right should do the same, but jump only by unfiltered nodes
