Feat: Single Settings Page + Default Naming Series for payment Entry

[Madcheese101]

• Added a new doctype called POSAwesome Settings for Global Settings across POS Profiles.
• Added the ability to set a default naming series for payment entries from the POSAwesome (can be set at the new doc - POSAwesome Settings)
• If the default naming series is set in the POSAwesome Settings (the new doc) then it will use that instead of the default value of the original field in the payment entry doctype.

How this settings will handle multi company scenario?
Do you think also we should add option for Sales invoice naming series?
And maybe we should add them in POS Profile ?

• I am not very sure how this works in multi-company scenarios, however, this gets the metadata of the doctype after applying the property setters from Property Setter fields.
• You already can select the default naming series for a sales invoice from POS Profile.
• I decided to add them to a separate settings page since it would be applied for all pos profiles in a company, however, if this doesn't work well with a multi-company scenario then placing it in POS Profile would solve the issue.
