mrtg treeview

Allow null x and y size - this allows deletion of the default values

CLEANUP

Add first pass at a javascript indexpage

Identify ourselves in the metadata and add to installation target

Hide non public objects, rename global items to be more obvious

Remove unused code, update output to be purely json

Add tags to each graph, export all time ranges for each graph, json beautification

Structure of indexmrtg is now mostly right

output indexmrtg to json, start renaming fields

Rip out most of the old file's guts from indexmrtg
