Removed ignorecase as smartcase is used instead
(and overrides 'set smartcase' anyway)
Various small changes:
* Don't cut words on wrap
* better description for noshowmode
* Disable startup message
* Better remapping for F1, now uses <nop> instead of <ESC>.
  F1 shouldn't be used for ESC, thus it's a bad idea to even bind it as such.
