[Idea] Customizing Time Ranges

Love blazer. I use it on all my projects.

One thing I've been wanting is more time ranges in the time range picker.

Currently these are the ranges:

blazer/app/views/blazer/_variables.html.erb

Lines 90 to 94 in 41f8df2

    
           ranges: { 
        
            "Today": [dateStr(), dateStr()], 
        
            "Last 7 Days": [dateStr(6), dateStr()], 
        
            "Last 30 Days": [dateStr(29), dateStr()] 
        
           },

I'd love to add more (similar to quickbooks, see below) if that's ok or make a way for it to be configurable from blazer.yml.

I don't think we'd need all of the options below, but perhaps adding this week, (month, quarter, year), last week (month, quarter, year), along with "X to date" on those (like year to date) would be really helpful.

Any opposition to this or things I should know prior to cutting a PR?

Quickbooks drop down

Apologies. I just saw https://github.com/ankane/blazer/pull/313/files.

	ranges: {
	"Today": [dateStr(), dateStr()],
	"Last 7 Days": [dateStr(6), dateStr()],
	"Last 30 Days": [dateStr(29), dateStr()]
	},
