Change display name wording

fixes #502

Relates to #538

add notice and rainbownotice commands

makes nheko appear at the top, if you search for it as well as TWIM match the twim room

No idea, how that happened and where it came from

Use qsTr() for strings

add /rainbow command

Fix build: refactor variables to avoid same names in a scope
