Place century selection in browse search parameters of URL, et al.

[craigsapp]

The composer search field is copied to the URL:

https://polishscores.org/?c=Asola%2C%20Giovanni%20Matteo

But the century select menu does not do this:

The genre selection also needs copying to the URL:

Genre (and probably most other search fields are read from the URL):

https://polishscores.org/?g=Christmas

Library is copied to URL:

Instrument selection needs to copy to the URL:

Title search field copies to the URL, but not lyrics:

Also pitch searches need it:

As well as tonic:

And mode:

[craigsapp]

Add search fields to this.VARS.SEARCH_URL for other field besides composer, siglum and title:

doBrowseSearch.js:  this.updateBrowseUrl(this.VARS.SEARCH_URL);
filterByComposer.js:        this.VARS.SEARCH_URL.c = target;
filterBySiglum.js:      this.VARS.SEARCH_URL.s = target;
filterByTitle.js:       this.VARS.SEARCH_URL.t = target;

CGI parameters for search fields (from getCgiParameters.js):

param	name
c	composer
g	genre
l	lyrics
p	pitch
s	siglum
t	title
y	century

New ones to add:

param	name
i	instrument
k	tonic (key)
m	mode (e.g.: major, minor, lydian)

Commit https://github.com/craigsapp/website-polish-scores/commit/07983ddefd69505cdb096ad27a261cc4b1743ec1 adds search to URL for all browse search fields.

Still need to implement i, k, and m parsing from incoming URL.

Example covering all but lyrics:

https://polishscores.org?c=Paderewski%2C%20Ignacy%20Jan&y=18xx&s=PL-Wumfc&g=Etude&t=exercise&i=piano&p=cde&k=C&m=maj

Added parameters:	search field	parameter
composer	c=Paderewski%2C%20Ignacy%20Jan
century	y=18xx
siglum	s=PL-Wumfc
genre	g=Etude
text	t=exercise
instrument	i=piano
pitch	p=cde
tonic (key)	k=C
mode	m=maj
