Share from home screen

[DRosadoYew]

Almost every day i scroll through the list of Posts on the home screen just to find the ones i would like to read later (add to pocket).
Currently, you need to tap on the item and wait for the Post to load before you're able to share it. Even though PR #14 removes the need to wait for the Post to load, i think it would be useful to have a shortcut right from each item on the home screen.
As in issue #16, i'm not sure where i'd add the button. I see two main options:
1) Add a button to the cell view
Pros:

• Requires one tap only
• It's right there

Cons:

• Adds clutter

2) Add a swipe gesture
Pros:

• Keeps the current white space on the cell
• You'll have an easy place to put other shortcuts

Cons:

• Requires one more gesture than 1)
• Hard to know it's there

@bonzoq do you have any thoughts on this? Thanks
