Add more API mappings

[Grazfather]

I am working on a simple IDA plugin and found your IDAW wrapper (See hugsy/gef#510)

There are a bunch of mappings that could be added to get it to work better. See https://www.hex-rays.com/products/ida/support/ida74_idapython_no_bc695_porting_guide.shtml

A tiny subset, that works for my plugin, at least:

        'GetBptEA' : 'get_bpt_ea',
        'GetBptQty' : 'get_bpt_qty',
        'GetColor' : 'get_color',
        'Jump' : 'jumpto',
        'MakeComm' : 'set_cmt',
        'MakeName' : 'set_name',
        'SetColor' : 'set_color',

Look at hugsy/gef#553. The above doesn't work perfectly because some commands take extra args. My linked PR fixes this, and I think does the safe_generator thing better, feel free to pilfer.

Thanks @Grazfather for the advices. We will address the problem with a new plugin version compatible with IDA 7.3+. The issue is related to #30.
