Bloatedness ... memory chewage

• MySpell checking – a huge beast [recently un-fixed]

• • by mmapping the dictionary & using a simpler hash
  • 3.5Mb -> 1Mb of (non-shared) memory usage at least 1Mb saved for single-user case.
  • fix in ooo-build, not up-stream yet

• exploding types.rdb – mmapped but ...

• • went from 3.5Mb in 1.1.x to 6.1Mb in 2.0 – why ? [GHEX ...]

• images.zip – much better vs. 1.1.x resources

• • unfortunately doubles size of .zip with (~never used a11y) icons (wasting 500Kb core to store .zip directory). [.zip stamp]
  • fix implementing icon theming (in ooo-build, festering in cws)
