F5 debug display: Reformat and remove some information (#6125)

For consistency return to 'FPS =', add comma before FPS.
Remove 'R' from 'range_all' as may be re-keymapped.
Remove inconsistent brackets from 'range_all'.
Change 'v_range' to 'view_range'.
Add 'pos = ' before co-ordinates.
Add spaces around '=' in yaw display.
Remove brackets from around 'yaw' and 'seed'.
Move 'pointing_at' to 3rd line.
Remove 'param1' (0 for all solid nodes and unreadable for light sources due to
light bank encoding).
Remove file name of pointed node top tile (this also removes the need to get
ContentFeatures for the node, slightly improving performance).
Replace quotes around node data with brackets, looks better and more consistent.

Add 'guitext3' for third line.
Use 'setVisible' for all 3 lines to control the setting of each text rectangle.
Improve logic of 3rd line to only run code it needs to depending on whether
pointing data is avaialble and whether node is not 'ignore' and not 'unknown'.
