New Template Wizard support
This changeset adds several new templates, to create a new project, a
new activity, a new custom view, etc.
More importantly, it contains support for these wizards (and the
corresponding code generation) to be driven by templates.
A wizard contains metadata which provides a name, description and icon
for the template, as well as a list of parameters, along with type and
constraint metadata for those parameters. When a wizard is created for
this template, it automatically adds UI elements to input the
parameters and to validate the input. Parameters can also specify
their default values as templated expressions using the other
variables on the page, so in the New Blank Activity wizard for
example, editing the activity name automatically updates the suggested
layout name, by repeatedly evaluating a template expression to compute
a layout name from an activity name.
There's a recipe file for each template which states what actions to
take to create the template. In addition to obviously copying
resources (such as icons and jar files) and instantiating templates
(to rewrite text using variables and FreeMarker logic), it can also
merge XML contents (to for example insert activity registration
metadata into the manifest file, or add string definitions to the
strings.xml file), and it can cause files to be opened when the
template is created.
Tne new wizards also use JFace's decorator support to provide help and
to mark text fields that contain errors, when one or more of the page
fields do not validate, as well as to show tip text along the bottom
of the page. One example of this is that it explains what a "package
name" is when the package field has focus.
This changeset also contains a "Template Development Wizard" which
lets you point to a local directory containing a template definition,
and run a test wizard from there. This is useful for developing,
debugging and testing templates.
