[FIX] website: allow height control over inline embed code snippets

The embed code snippet (introduced at [1]) comes with a default
"half-screen" min-height. Since [2] (patched with [3]), the min-height
option is not shown anymore for snippets which are dropped in other
snippets ("inline" snippets)... and [4] actually made the embed code
snippet an "inline" one later on. The problem is that once dropped as
an "inline" one, the embed code snippet had thus a "half-screen"
min-height which was impossible to remove.

This commit patches the snippet so that it does not use a default
"half-screen" min-height but default paddings which work both as
"main" and "inline" snippets. The user can still use the min-height
option by himself if he wants to.
