Implement "save as" functionality

[TheCorio]

Suggestion: binary serialization to *.bs format.

If your suggestion comes true i think that it will make sense to rename Save as to Save

[TheCorio]

"Save" and "Save as" are different functionalities:
"Save" - saves changes to currently opened project;
"Save as" - saves project to user defined location.

So yes. Both of this should be done. Will modify mockups and issues tomorrow.

In addition you can choose particular type of file to save. It is what i exactly mean in previous comment

[TheCorio]

In our application we don't give this choice to user.
