Batch insert new posts to stream

- This gives the user the sense of what he/she is currently viewing
- The hover/selected are the same right now. Needs to change.
- Need to find a more meaningful place for `markSelected`

Moved markSelected to app.views.Stream

- Removes duplication
- All streams create this view, and this seems to do some setup on
  initializing, which is a good place to markNavSelected

Changing highlight on hover to 'black' instead of the blue

- The blue was a little intruisive
- Also fixes the vertical alignment issue

Changing the background to bluebg on hover

change bitcoin_wallet_id to bitcoin_address

Prevent overflow of strings too long on single page view

* It's broken for those that would benefit from it (postgres users)
* It's broken in the design: Reading it from the config requires bundle exec ruby, which requires it being set properly

It is better to call it an address than a wallet ID, because the latter may
confuse Bitcoin users who conflate the two. They are not the same.

Also adds convenience method to handle the deprecated variable.

Should make situations like #4468 less frequent

Refactored the colors palette a little more

to specify why users got a 404, and possibly leaking information while doing this

See discussion in #3717 for rationale on not implementing specific HTTP codes
This solves around #3717 and #3728

Adjusting travis breakage

- Introduced text-dark-grey = #666666
- Converted text colors #777777 and #555555 to text-dark-grey
- Removed header-grey in favor of text-grey
- Included colors in a couple of files where it was missing
- Categorized the colors in the palette based on the contexts of usage

Substituting -grey for #999

Moving #888 text color to -grey

Adding border-dark-grey

Removing border-dark-grey from places where it isn't appropriate

Fix size of images in the SPV

Fix preview with more than one mention

- Each time a stream is rendered, other lists are emtied
- Using Backbone.history.fragment to detect active stream
- hideInactiveStreamLists is best pushed into a before/after filter

Added tests for hideInactiveStreamLists

Error 500 when visit probile mobile and logged out. Fix #4458

- This action needn't be performed when all notifications are read,
  hence disabling it is a good practice
- Added a link-disabled-color
- Used css pointer-events to disable clicking on the link

Preventing default on click for the mark_all_read_link

- avoiding the use of pointer-events
- setting up disabled only for mark_all_read_link

Moved disabling of the link to a global handler

- Added disabled class to the button in /notifications when all are read
- Styled the disabled button
- Adding disabled class after completion of ajaxRequest

The issue only shows if you have a send :exec, user_input in your
codebase, neither we nor Sidekiq does that.

	Changelog.md

- Earlier, triple-clicking or drag & select had to be performed to select
- Should consider a copy button

Moving away from the inline onClick handler

It didn't feel right to be writing js in a helper.

Refactoring setupInviteLinks into a sidebar Backbone View

Fix style in profile sidebar / contacts

- Pulled out the existing palette in _mixins
- Took a stab at naming greys after their usage count in contexts
- Replaced #a40802 with #a80000, since they are very close and $red was already in the palette

Missed importing 'colors' in a couple of places

Removing a redefined  in favor of  in colors.css.scss

Fixing missed imports #2

Renamed $background to $background-white

Explicitly calling out the color of the background, since we have many
background colors

Revert "bump recommended rubygems version"
