Parameter to set distance between legend columns

[omuelle]

The legend columns of Gesamtschweiz D12 and D12 are very close to each other, would be nice to have a parameter to increase the distance between them.

[HomoCodens]

This is done by base legend. Looks like the only parameter to affect this distance is text.width which specifies the width of all legend entries in user coordinates (e.g. a value of 1 means the legends would be as wide as one year in the plot).

See the referencing commit for a version with this parameter. The best I could do was:

tsl <- generate_random_ts(4, starts = 2013, lengths = 6*12)
names(tsl) <- c("Orig", "D11", "Gesamtschweiz D12", "D12")
tsplot(tsl, theme = init_tsplot_theme(legend_col = 4, legend_text.width = 1.37))

Not so sure this is a smart addition though, finding the value involves lots of trial and error.
