feat(run): Tomcat local run configuration (#392)

Adds Tomcat Server › Local run configurations for WAR applications: installation validation and version detection, Maven/Gradle WAR artifact discovery and build before launch, WAR file or exploded-directory deployment, context path and HTTP port, project JDK or a chosen JRE, VM options, environment variables and opening the browser.

Each configuration runs with its own CATALINA_BASE in the project cache (HTTP, shutdown and local JMX ports configured there); Stop requests a clean shutdown before the usual process timeout. Debug attaches the Java debugger over JDWP. Update Application (Cmd+F10) updates resources, classes and resources with HotSwap, redeploys or restarts the server. Configurations are grouped under Tomcat Server in the configuration tree and Services.

Not verified on a real Windows machine; command construction is unit tested.

Fixes #205
