pspg 4.6.0 released

I released pspg 4.6.0 There are few interesting features against lastly mentioned here 4.3.0 release: 

• fix stream mode on apple 
• new option --menu-always - top bar menu will be visible always
• fix some visual artefacts for some special cases when user uses style with border = 1
• new query stream mode.

Query stream mode is designed for using from text editors, that can start pspg in separate terminal in permanent mode. In query stream mode the pspg works like Postgres client, reads queries from pipe, executes it and draws an result. The queries are separated by Group Separated char (GS - 0x1D).
