Add notation configuration parameters to URL

[craigsapp]

Example:

https://polishscores.org/?id=pl-wumfc--n2100--001-012

Add configuration parameters to automatically set configuration options, such as:

https://polishscores.org/?id=pl-wumfc--n2100--001-012&config=MsOcAs

Where config=MsOcAs are the configuration options to set:

Probable codes for options:

Code	Meaning
Ms	Modern stemming
Ml	Modern letters
Oc	Only bass/treble clefs
An	Show all notes
Er	Expand repeat marks
As	Automatic stemming
Ss	Sounding score
Ts	Tight spacing
Hs	Hide sic warnings
Sa	Apply sic corrections
Fs	First system only
Sc	Show custodes
Tr{+P5}	Transposition
Tp{140}	Tempo scaling
Fi{extract -k 1}	Filter

Also update the URL with any activated configuration options.

This will allow saving/sending links to the score with a particular view state.

It would also might be useful to add to starred works (in that case other configuration options should be cleared in the current session when the work is loaded from the starred list).

Commit 94dd269 adds a parsing function to read configuration parameters from the URL.

Example: https://polishscores.org/?id=pl-sa--481-a-viii-121--033&config=MsErAs

Checking transposition, first original:

https://polishscores.org/?id=pl-sa--481-a-viii-121--033

Now transposed down a minor third, and automatic stem direction added:

https://polishscores.org/?id=pl-sa--481-a-viii-121--033&config=AsTr{-m3}

Also applying free-form filter in configuration panel:

https://polishscores.org/?id=pl-sa--481-a-viii-121--033&config=AsTr{-m3}Fi{extract%20-s1}

Configuration settings:

Expand repeats option:

https://polishscores.org/?id=pl-sa--481-a-viii-121--033&config=Er

Commit 98f26ec updates the URL with the configuration settings:

https://polishscores.org/?id=pl-wumfc--r288

Checking the "Hide sic warnings" and Transposing up a perfect fifth:

Code	Meaning
Hs	Hide sic warnings
Tr_+P5_	Transpose up a perfect 5th

https://polishscores.org/?id=pl-wumfc--r288&config=HsTr_+P5_

I changed { and } to _ so that they do not need to be unescaped in the URL. I forced + to not escape. Maybe this can be used for { and } in a similar manner since they are also not important to be escaped.

[craigsapp]

Transpose is not loading from URL, probably due to change in { and } usage. Probably return to this system anyway.

Test of free-form filter (extract bottom staff of score):
