This commit improves templates readability, since all of them use consistent
indent with all template command blocks indented too.
1. Indents both HTML containers such as <div>, <p> and Go HTML template blocks
such as {{if}} {{with}}
2. Cleans all trailing white-space
3. Adds trailing last line-break to each file
Most commit in Git are expected to follow standard of single header line,
followed by description paragraphs, separated by empty line from previous block.
Previously Gogs were treating everything as single header. Now we are trying to
render only first line as header, but following lines (description chunks) as a
verbatim.
Current green SHA1 labels are more pronounced than other UI elements attracting
attention as if they were most important thing in the UI, while they are not as
important, especially without real Git client.
Using grey SHA1 labels makes the UI more balanced, less aggressive and lets
user to focus on other content elements.
NOTE: Neither GitHub or Bitbucket uses so heavy pronunciation as Gogs.
This uses a CSS trick making first th to be relative block with width equal to
first two columns, effectively working around inability to use colspan="2" on
first row that was breaking "fixed-layout" for tables.
Also use grey header for last-commit SHA1 tag.
Instead using own ellipsis, uses Semantic UI fixed single line table which
effectively applies ellipsis to all overflowing table cells.
NOTE: File list cannot use colspan="2" for 1st "Last commit" elements,
otherwise layout breaks with fixed table.
