Implement window manipulation CSI sequences

[vadymeng0]

Description

This PR implements CSI sequences for manipulating the Aminal window. I took the specification there: http://www.xfree86.org/4.7.0/ctlseqs.html (search for Window manipulation on the page)

Several sequences were not implemented:

• CSI 6 t - Lower the window to the bottom of the stacking order - Because the GLFW library does not have such a feature
• CSI 7 t - Refresh the window - Because Aminal continuously refreshes itself. By the way, it looks like on Windows this sequence is handled by the system.
• CSI 19 t - Report screen size in characters
• CSI 20 t - Report the window icon label - Because the GLFW library does not have such a feature
• CSI 21 t - Report the window title - Because the GLFW library does not have such a feature

Aminal logs reasonanble error message on each non-implemented sequence.

Fixes # 237 (partially)

Type of change

• [X] New feature (non-breaking change which adds functionality)

How Has This Been Tested?

It was tested by manually issuing the control sequences.

Test Configuration:

• OS: Windows and Linux

@nikitar020 strange, but can't see button to restart failed job in Travis

@MaxRis It started to fail randomly after I merged recent changes from the develop branch. Btw, the develop branch does the same.

@MaxRis So I re-run the build three times and it seems always succeeding. I think this PR can be merged.
