feat(tabs): add ability to set tab name (#212)

* send all tabs in vec

* works but no input filtering

* add event types

* add event handler for tab events

* fmt fixups

* update tab name in place, and escape rename works

* rename handle_tab_event handle_tab_rename_keypress

* handle empty new_name when renaming

* fix(tabs): pad active tab name too

* fix(tabs): report proper length

* fix(tabs): always render active tab

* style(fmt): rustfmt
