Separate logo drawing and status-lines drawing about synth-shell

[andresgongora]

I'm working on an edited version of status.sh - It does not solve this issue, but it will make it MUCH easier to implement any option we might choose to; be it a matrix implementation or a smart multirow with overlapping text.

I've taken a look at your exit code suggestion, and its perfect!! Great idea!! :D

So, I'm back from another journey; but I had time to think about the problem and put together all the pieces from our past discussion. The idea would be as follows:

1. Get terminal info: such as size, to compute where we want the logo and the info elements. On a wide terminal, they might be plotted further apart, on a narrow terminal (e.g. 80 chars broad), they should be packed tightly together. On a super narrow terminal, the logo should be omitted altogether.

2. Draw the logo

   1. Load the logo as a single string, where the end of the logo would obviously be delimited by a \n.
   2. Move the cursor to the position where we want the logo to start (upper left corner).
   3. Reformat the logo (sed, tr, awk...) by replacing the new line characters \n with an escape character that tells the cursor to go to position [i+1,c]; where i+1 is such that sequential lines are drawn, and c is the first column where we want to draw the logo.
   4. Print the reformatted logo. Each new line will start at the correct position.

3. Draw info

   1. Read a configuration line that contains the info elements that the user wants to plot, and their order. For example stats="os, cpu, gpu, user" means that the first info line should be OS related info, next line should be CPU info, next line should be GPU info (not implemented yet), and the last should be the USER/HOST info. This way, the user may omit or reorder the lines as wished.
   2. For each word in the above configuration line, call a function that is basically a big switch-case that then calls the appropriate printing helper. But before printing, the cursor is relocated to the current position.

Solved in #105.
Realized there is a bug (maybe always there?), described in #106.
