This reverts commit aab385d0.

add lora hashes to infotext
when pasting infotext, use infotext's lora hashes to find local loras for <lora:xxx:1> entries whose hashes match loras the user has

never refer to lora by an alias if multiple loras have same alias or the alias is called none

remove LRU from #8366 because I don't know why it's there

update readme to reflect some recent changes

rework of hypernets: rather than via settings, hypernets are added directly to prompt as <hypernet:name:weight>
