Add option to allocate the samples in fake_dc()

Browse source 
We (ab)use fake_dc() to create a pleasing profile for a manually added
dive. Based on it's intended use, fake_dc() simply handed back a dc
structure that pointed at staticly allocated samples - that's obviously
(now that I think about it) going to blow up in my face if I edit a
manually added dive more than once.

So now we have an option for fake_dc() to actually allocate the samples -
this way the rest of the code can treat these samples as we would treat
samples created any other way. We can free them and replace them with a
new set.
