new stuff from mEDi_S

hi Omegaice,

here 2 new ideas
1. store only when changes (save not on all clicks a new config)
2. notify changes ( show the view range as notify on changes + config option)

sorry github allow me not to add only the one patch in this pull request

https://help.github.com/articles/merging-a-pull-request#patch-and-apply
https://github.com/Omegaice/WOTTankRanges/pull/11.patch
only the last part is from interesting
the copy paste make now many problems ;/

git pull https://github.com/mEDI-S/WOTTankRanges.git 71c16cb7a859c0cccb41df0594417100a9eafdd9
