In preparation for adding more text types, refactor the common fields
into a new structure. This will allow common code to be used.

Open the lineedit and add a few characters, to check that things look
right.

At present when the user moves to a new menu item, the menu code
handles this immediately. This means it is not possible to use an expo
action to effect the same change.

Update this so that EXPOACT_POINT_ITEM is handled in cedit_do_action().

Expand the test to cover this.

Check the rendering output when adding characters to a line-edit object.

Add a separate test to check behaviour when starting with existing text
in the lineedit. The cursor should start at the end.

At present this function locates it own video device. Pass it in to
provide more flexibility.

Refactor the action-processing code into a new cedit_do_action()
function so we can call it from a test. Check moving to a new field and
opening the menu, to ensure that rendering is correct.

Update the cedit read/write functions to support menu items with
values.

Set aside some expo IDs for 'save' and 'discard' buttons. This avoids
needing to store the IDs for these. Adjust the documentation and expo
tool for the new EXPOID_BASE_ID value.

Ignore these objects when saving and loading the cedit, since they do
not contain real data.

Adjust 'cedit run' to return failure when the user exits the expo
without saving. Update the test for this change as well.

Set this flag rather than doing things manually in the test.

Drop unnecessary calls to console_record_reset_enable()

As part of bringing the master branch back in to next, we need to allow
for all of these changes to exist here.
