Make/modify build chain

[kateliev]

After todays build i realized that some updates to our tools as well as making some simple ones will do us good.

##To do: Preflight tool:

• [x] Add .loclBGR and *.alt to safe suffix list;
• [x] Add automated Round, Decompose, Convert to TT actions (and button);

Unify CLI Build steps under single shell script:

• [ ] Powershell for Win users;
• [ ] Bash for Mac/Linux users;
