Add Feature: Shared Workflow Definitions

Background: so far, xowf stored workflow definitions in the workflow

context, which is generated for every instantiated workflow instance

due to the needs of the State Pattern. While the old approach works

perfectly fine, when pre request only one or a few workflow instances

are created, but is inefficient, when e.g. 100 or more instances of

the workflow definition are created.

Now, the instances can share the definition, which is shared based on

the revision_id of the workflow FormPage.

OLD: obj <-> obj::wf_ctx

NEW: obj <-> obj::wf_ctx <(n)----> wf_definition

OLD scenario:

- the wf_definition was part of the context (no distinction)

- navigation from wf_ctx (and wf_definition) to object was possible

via "info parent"

NEW scenario:

- the wf_definition is separate

- one wf_definition can be used for multiple wf_ctx

- new methods are required instead of "info parent"

to navigate between these cooperating objects

* xowf::WorkflowPage.wf_context

* xowf::WorkflowConstruct.wf_context

* xowf::Context.wf_container

The navigation from a WorkflowConstruct (e.g. State) to the wf_ctx

is slow and fragile if not following usual programming conventions

and should e avoided (the methods of these constructs have the obj

passed in, so this path should not be necessary in most situations)

- as long the contents of the wf_container is constant, it can be

shared in the per-thread cache.

For now, the new feature is turned off by default via variable

::xowf::sharedWorkflowDefinition, but this will change in the future.

Make so that refreshing of theming subsite parameters doesn't include locally modified subsites

This includes also moving of logic to identify local modifications in a proc

Regenerate ADP files

Add feature: overwrite generated ADP files only when necessary

Cases might be:

- ADP file list

- Generator updated

Fix: close link target (<a name ...>); backport from HEAD

Fix: close link target (<a name ...>)

Added procs to quickly issue refresh of subsite theme parameters from current theme defaults. This is useful in a context with many subsites using the same theme, when desired behavior at upgrade is to have them reload all parameters automatically.
