HaikuDepot: reflect package install changes

This update will mean that HaikuDepot is able to detect
install / uninstall actions on packages at the system
level and reflect this in the user interface.

Fixes #15879, #15994 and #15046.
Relates to #11674.

Also cleans up disused code in the WorkStatusView.

HaikuDepot: Check User Auth on Start

The user might have changed their authentication details
on the server and the client won't detect this until
they go to do something. Instead, if possible, check
this as the client starts. Also check that the user has
agreed to the current user usage conditions.

As a side-effect this generalizes the logic for process
coordination in the main window and also fixes some bugs
in the main window's progress display as the application
starts.

Relates to #15209

HaikuDepot: Improved translatability using BStringFormat

The string "(%count% more to download)" is sensitive to
different plural forms in other languages. For example, in
German one could have:
"1 weiterer Download" and
"12 weitere Downloads"

HaikuDepot: Add accidentally removed space

Re-add the space between currently downloaded package and number
of packages to be downloaded in status view.

I accidentally removed that in hrev52432.

Fix missing localization

This addresses some of what's reported in ticket #14637.

* Keymap preferences: Localize key labels. Translators have
to be careful not too use too long words here...

* Media preferences: Fix typo "SoundFonts" -> "SoundFont"
The two popup menus, Video input/output, both use "<none>",
which when the catkeys are collected is reduced to one item.
Apparently, Italian likes to have different tranlsations for
them. I hope to fix that by using B_TRANSLATE_COMMENT with
differing comments. Not sure if that'll work...

* Network preferences: Localize "on/off" and "Enable/Disable"
in the Services.

* Repositories preferences:
Add RepoRow.cpp to DoCatalogs.

* Shortcuts preferences: Localize "Left/Right/Both/Either/None"

* Bluetooth replicant: Localize menu items and alerts.

* DeskCalc: Localize button names.

* HaikuDepot:
- Use BStringFormat and variables to replace for the WorkStatusView.
- Put package name in single quotes; nicer if you have package names
with spaces.
- Avoid leading and trailing spaces in translatable strings. Those
can be overlooked b the translator.
- Use B_UTF8_ELLIPSIS instead of "...".

[Haikudepot] Change barberpole colors

* Feel free to tweak tint and other parameters
* As suggested by waddlesplash this should extend the progressbar
* Should fix #13808

HaikuDepot: make status bar smaller

* As requested in #13808

* Thanks to Janus for the tip with the SetBarHeight

HaikuDepot: add work status view

* Add new WorkStatusView which keeps the user informed about what's
happening. It's a status bar at the bottom of the window which
shows on the left side either a spinning barber pole (for
operations without a progress), or a progress bar (for download
progress). Next to that is a text view showing a descriptive
status text.

* Currently, it will notify of the following operations:
- Repository refresh (barber pole)
- Background packet actions, like preparation of install or uninstall
(barber pole)
- Package downloads, including downloads of dependencies (progress
bar). Status text indicates the name of the package currently
being downloaded (if any), and how many more packages are queued
for download after it (if any).

* Hooks into PackageListView to be notified of package status changes
(such as becoming pending or download progress)

* When the package currently being downloaded is also selected in the
list view, the user sees the progress bar in WorkStatusView
as well as the one in the PackageInfoView, which is redundant. This
still needs a good solution...
