Actually properties height and width are QDialog ones, just rename them
to ones with `item` prefix. No configuration keys were changed.
Update translations as well.
* translation update
* fix broken build with gcc (#87). The issue was reproduced only with
gcc build and has been resolved by just replacing C-like `isnan` to
`std::isnan`
I've added 'optimize' option (by default true). If it options is set
then sources will be checked if they are required (with dependencies if
any). And if they are not required they will be dropped by using common
mechanism.
Please note that if this option enabled the following features (at the
moment) will be unavailable:
* key request from context menu (from configuration interface it still works)
* notifications event if sources on which notification is not connected
I suppose this commit will increase performance in about 4-5 times.
I suppose the better way is to move weather adaptor to another open
weather engine despite the fact that OWM has provided me a special FOSS
permissions. I've changed weather provider to Yahoo! Weather because
there is no good way to provide my own API key to end-users except for
being compiled to the source code.
In other hand this solution leads to the fact that humidity and
atmosphere pressure is not available for forecast more. And moreover
pressure units has been changed for current weather.
+ fix possible memory leak in dataengine aggregator
+ add "special thanks" group to acknoledgment tab
