Replace PurpleIdleUiOps with the PurpleIdleUi Interface

This continues our path down replacing the UiOps with Interfaces so that
developers can write user interfaces in other languages using gobject
introspection.

Testing Done:
Ran pidgin3 and set it to auto idle after 1 minute of system idle time. This attempted to query xscreen saver, but something didn't work there, but that's been happening before this change. Not sure if it's my system or the code just needs fixing.

Ran finch3 set idle time to 1 minute and verified that it set me to away after that minute.

I also used the libpurple idle time for both pidgin3 and finch3 and verified they continued to work as well.

# Purple, Pidgin and Finch
libpurple is a library intended to be used by programmers seeking to write an
IM client that connects to many IM networks. It comes with support for Bonjour,
IRC, and XMPP, among others and there are many more networks supported via
[third party plugins](https://pidgin.im/plugins/).
Pidgin is a graphical IM client written in C, which uses the GTK toolkit.
Finch is a text-based IM client written in C, which uses
[libgnt](https://keep.imfreedom.org/libgnt/libgnt).
These programs are not endorsed by, nor affiliated with, any proprietary
instant messaging company in any way.

See AUTHORS and COPYRIGHT for the list of contributors.
## Building
Pidgin uses [Meson](https://mesonbuild.com) as its build system. There is a
long list of dependencies that is not currently documented here due to
differences in package names across operating systems. We plan to fix this
soon, if you have any suggestions on how to handle this, please let us know.
You can quickly build Pidgin with the following commands:
```
meson build
cd build
ninja
ninja install
```
There are quite a few options for the build that you can view by running
`meson configure` in your build directory. You can specify the options when
running meson like the following:
```
meson -Ddebug=true build
```
If you have already run `meson` you can use `meson configure`:
```
cd build
meson configure -Ddebug=true
```
## Running
Currently Pidgin can not be run from a build directory, which means you must
install it first. Once you've done that, you only need to run `pidgin3` or
`finch3`. If it fails to launch you may need to run `ldconfig` as root.
To get started, simply add a new account.

## Plugins
libpurple, Pidgin, and Finch ship with a number of plugins, but you can find
additional third party plugins at
[pidgin.im/plugins](https://pidgin.im/plugins).
## Developing
You can find more information about Pidgin development in the
[development section](https://pidgin.im/development/) of our website.
