* massive changes inside includes, drop unused definitions
* rewrite some initialization methods to avoid additional
freeing/allocation
* drop some explicit destructors calls
* 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
* 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
This commits series introduces bars which may be calculated from any
custom formula. For a start I've renamed $bar*tag to $bar* and add new
configuration parameters to graphical items.
* Initial syntax is the following:
* $template{{ some JS code here }} - simple template based on JS
code inside. It works the same as lambda functions, but calculates
only once.
* aw_count(regex) - keys count found for given regex
* aw_keys(regex, [separator]) - keys found for given regex and
joined by using given separator
* aw_names(regex, [separator]) - key names found for given regex and
joined by using given separator (the same as previous but w\o $)
The template and function syntax may be changed before release.
* replace `foreach` to `for (auto foo : bar)` and update CONTRIBUTING.md
accordingly
