feat(ui): The status bar indicates that the panes are full screen and how many hidden panes are (#450)

* fix(ui): offset content after viewport construction

* Added the feature to display fullscreen information on the second line of the status-bar.

* fix(strider): update host mount-point

* fix(plugin): create missing data directories as needed

* feat(layout): specify only tab name in `tabs` section (#722)

Allow specifying only the tab name in the `tabs` section

- For example this is now possible:
```
tabs:
  - name: first
    parts:
      - direction: Vertical
      - direction: Vertical
  - name: second
  - name: third
```
  For that the tab section defaults the direction to
  `direction::Horizontal`

- Adds an error upon specifying a tab name inside the `parts` section
  of the tab-layout

* docs(changelog): Solely name tab in `tabs` section

* feature(release): Copy default config to the examples folder on release (#736)

fixes #733

* docs(changelog): Copy example config on release

* Update default config (#737)

* feat(plugin): add manifest to allow for plugin configuration (#660)

* feat(plugins-manifest): Add a plugins manifest to allow for more configuration of plugins

* refactor(plugins-manifest): Better storage of plugin metadata in wasm_vm

* fix(plugins-manifest): Inherit permissions from run configuration

* refactor(plugins-manifest): Rename things for more clarity

- The Plugins/Plugin structs had "Config" appended to them to clarify
  that they're metadata about plugins, and not the plugins themselves.

- The PluginType::OncePerPane variant was renamed to be just
  PluginType::Pane, and the documentation clarified to explain what it
  is.

- The "service" nomenclature was completely removed in favor of
  "headless".

* refactor(plugins-manifest): Move security warning into start plugin

* refactor(plugins-manifest): Remove hack in favor of standard method

* refactor(plugins-manifest): Change display of plugin location

The only time that a plugin location is displayed in Zellij is the
border of the pane. Having `zellij:strider` display instead of just
`strider` was a little annoying, so we're stripping out the scheme
information from a locations display.

* refactor(plugins-manifest): Add a little more documentation

* fix(plugins-manifest): Formatting
