CR typechecking options are now application-level.
The solution j.m.c.ideaplugin contains the code responsible
for accessing and setting the options. This solution is loaded
as IDEA plugin on deploy and as regular module in source project.
Also merge code from two modules into j.m.c.typechecking.
Config is an application-level "component" initialized from an application plugin.
All usages on application/project-level should declare explicit dependency on it.
Tests can either create a new instance or access the shared one.
A reusable Config app component to be responsible for all level of configurations: default/system/user/ui.
Swith to Config interface instead of map<string,Object> for options.
Add an UI option to control whether trace is enabled.
