Add wxAuiManager::AlwaysUsesLiveResize()

Browse Source 
This allows to check if it's worth specifying wxAUI_MGR_LIVE_RESIZE or
not and allows to get rid of the corresponding menu item in the sample
if it doesn't do anything anyhow.

/**
Returns true if windows are resized live.
Live resizing behaviour is specified by wxAUI_MGR_LIVE_RESIZE flag,
however some platforms (currently wxOSX) ignore it and always use live
resizing because this is the only implemented resize mode.
This function combines the check for AlwaysUsesLiveResize() and, for
the platforms where live resizing is optional, the check for
wxAUI_MGR_LIVE_RESIZE flag.
Using this accessor allows to verify whether live resizing is being
actually used.
