* allow decimal in percent templates

* release note

* add template to set x month average

* error on 0

* note

* lint

This is a more elegant way of implementing a month ahead version of the
percent goals. To use it add the `previous` flag to the percent goal, ex
`#template 10% of previous Paycheck`.

Added the option to add a remainder goal template. This will use the
remaining available funds and dump them into the respective category.
There is optional weighting. The remainder templates will be forced to
the lowest priority as to run after all other templates.

Usage: `#template remainder <weight>` Add the template line to any
categories you want to catch any remaining funds such as savings. The
amount added to the category will equal
`remaining_budget/total_of_weights*weight`. The default weight is 1.

Add option to schedule templates to budget the full amount only in the
needed month. Default behavior stays the same of spreading the expense
out over the available range.

To use the option, use a template like `#template schedule full
SCHEDULE_NAME`


Also some minor cleanup.

This attempts to add priorities for goal templates and addresses most of
https://github.com/actualbudget/actual/issues/959

.

I couldn't find a good way to preserve both "Apply" and "Overwrite"
operations, so this PR does away with the current "Apply" action
behavior. Every box with a budgeted value will be overwritten if a
template goal is present.

The added syntax to define priorities is as follows:
#template    -- priority 0, highest priority
#template-1  --priority 1, 2nd highest priority
#template-2 --priority 2, 3rd highest priority
#template-N --priority N, as many as you'd like.

~~Leaving as a draft as this may not be the preferred implementation but
I wanted others to be able to try it with netlify.~~

Hi there, `Peg.js` is unmaintained, so I figure you all would appreciate
if I replaced it with the drop-in replacement of Peggy. This is work I
am breaking out of #918.

Peggy adds new features like source map support that we could use,
although I do not include that in this change-set. It may be useful for
debugging changes to the .pegjs file we have.e

Resolves issue https://github.com/actualbudget/actual/issues/888

* Dedupe loot-core webpack configs

* Swap to parsing using Peggy

* Actually record syntax errors

* Refactor template types

* Add notifications after applying the templates

* “Successfully”

* Try a Nearley grammar

* Revert "Try a Nearley grammar"

This reverts commit 1e11c07b855a492b905f1291c3eadd93f78ac3de.

Not going with this approach since the error messages are inscrutable.

* switch to PEG.js which has slightly better tooling support

* fix parser

* Fix error reporting

* Adjust grammar for better error messages

Also allow spaces between currency symbol and number

* Fix grammar

* Make #template prefix case insensitive

* Trailing commas

* Remove patch-package from loot-core
