This fixes a bunch of Swahili string bugs by stripping out unnecessary
prefixed whitespace.

This also introduces a fast language switch bar between English and
Swahili. It's not currently tested or gated behind a platform flag, but
both of these will be changed if the team decides to proceed with this
solution.

This adds support for opening concept cards from hints, solutions, and
other concept cards.

Fixes:
- Removed extra spacing around a few Swahili strings (all should now be
fixed).
- Replaced 'reveal' English wording with 'show'.
- Added a new event for logging voiceover pausing.
- Updated the play/pause voiceover events to include language codes.

Documentation and/or tests may not yet be completed.

With the learner study parameter enabled, admins can now force-complete
lessons on a per-profile basis for all profiles in the app. This
leverages the existing developer-only options menu so this isn't
something we would want to incorporate in the long-term without more
refinement (none of the UI strings are even translated).

This also adds Swahili translations for test topic 0. Some style changes
including support for a secondary button type. Updated the in-lesson
language switcher to use this style & to be gated behind the learner
study platform parameter.

And, fixes hint & solution header expanding to be the whole header and
not the whole card.

This also includes a rebuild of much of the hint/solution data flow
since the previous version had a lot of unnecessary complexity. It also
redefines the internal representation for solution answers (which makes
them type-safe during data retrieval time).

(The intent of this issue is being tracked separately and will be
addressed on this branch in a follow-up commit).

This includes:
- Post-merge fixes
- A change to make the switch lang button container transparent so that
the continue & submit buttons are still clickable through it
- A fix to work around a databinding bug that can sometimes cause a
crash that would be 100% reproducible for a specific build of the app
(since it's a bytecode-level issue)

Also, clean up component_colors.xml (noticed during PR self-review) and
miscellaneous other code health adjustments.

Also, fix a few issues that the new tests discovered.

- Fixes a test broken in Gradle.
- Repurposes a now unused color for the new secondary button style.
- Fixes landscape support in profile_edit_fragment for the new modify
progress flow.

This includes:
- Fixing image sizing issues
- Fixing bullet/numbered list formatting issues
- Moving the in-lesson Swahili language switcher to also be behind an
admin-configurable per-profile setting
- Logging a new event for when the in-lesson language switch button is
clicked
- Logging a new event for when the user exits a revision card
- Updating all events to include app/content/audio language settings for
the user
- Updating the in-lesson language switch button to only show if the
content of a card is available in Swahili
- Updating the switch-to-Swahili button's text to be in Swahili when the
rest of the strings are in English
- Fixing an issue with session ID to ensure it gets reset properly upon
profile login
- Fixing an issue where switching between tabs in the topic screen
wasn't actually logging events for the switches
- Introducing a new share button in the learner analytics screen to make
it easier to record per-device IDs

Miscellaneous other refactors and/or fixes were also done, as needed,
and per feedback.

Also, bump version codes to prepare for another Kenya-specific alpha
re-release.

Includes one small clean-up.

These were missed in Bazel since test targets were never originally
added for them.

Conflicts:

Also, fix the version code ordering for KitKat/Lollipop versions
(Lollipop should always take priority).
