It will use the configuration file `$AWHOME/custom.ini`, group `[Custom]`. One
custom key per string, key is custom key, value is any of available
standard data.
Formatters will be defined by using standard way.
Lets try to use own QueuedConnection type instead of default
AutoConnection. To implement it we need to disconnect all default slots
and reconnect them with specified connection type
* do not use private variables if there are special methods
* change macro call from `aw_*` to `aw_macro_*`
* add forgotten configuration reading/writting for list formatter
Macros should be declared as `aw_macro<name,arg1,arg2,...>{{macro body}}` and then
they may be used as `aw_name<arg1,arg2,...>{{}}`. It just puts `macro
body` to pattern and replaces arguments to provided ones according to
macro call. E.g.:
```
$aw_macro<test,phrase>{{phrase}}$aw_test<hello world>{{}}
```
will transform into
```
hello world
```
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.
* new tag - $tstime
* add summand parameter to float formatter
* drop version.h includes since it has been moved to awdebug.h (e.g. to
introduce BUILD_FUTURE guards easy in the future)
* drop c++14 requirements since it is not used
* move from enum to enum classes
* more intuitive graph building in GI
* allow X-AW-Direction property works with graphs and bars
more intuinitve configuration interface in graphicalitem. Improve code
for the future references (in case if new color type will be added).
Change X-AW-*Color values to ones with prefixes (added autoconversion
from old-version api)
