Merge pull request #77 from aheusingfeld/master

Suggestions for #70 and #56
Fixed #80 "Reply function broken"

Introduced a "coalesce" function to pick either "entry-text" or "reply-text" value.
Fixed #80 "Reply function broken"

- renamed "coalesce"to "first-non-nil" as it's more fitting
- introduced a "field-value" var to not calculate "first-non-nil" twice
Fixed #80 "Reply function broken"

- use "or" instead of "first-non-nil"
- handle/ reject requests with 'nil' or empty text values
#78 Re-added the char counter to the input field on top of the page
Fix #82: Image should replace the image link

1. The image link is now replaced by the <img> tag. Therefore the image is placed at the position in the text where the link has been before.
2. We now use jQuery's `.html()` function instead of the `.text()` function to read the .post-content and write it back afterwards. The reason is that the HTML of anchor tags/ links in the post content would be lost other wise as it is not returned by the `.text()` function.
removed obsolete file
layout refinement
if image is wider than viewport, scale-down image to viewport size
