Support to remove table prefix from entities when "--removePrefix table_prefix_ " is mentioned

[darklightcode]

First of all, I've started using this tool recently and it's wonderful, great job.

Would be good an option to remove a table_prefix before generating entities.
I decided to delete my entities files after i changed them alot, my case looks like this:

All good with the following:
TypeORM:

• entityPrefix = web_

Entities:

• Account
• User
• Session

Tables:

• web_account
• web_user
• web_session

As i said before, i deleted all the entities and used typeorm-model-generator to generate new ones, to my surprise the output was:

Not good, different files:
Entities:

• WebAccount
• WebUser
• WebSession

What is should have been:
Entities:

• Account
• User
• Session

Which turned my problem into another problem since my code was bound to the previous -unprefixed- entities, and this could be fixed with a new option to specify a table prefix and extract ONLY those tables. In the meantime i managed to fix it with a custom naming strategy, but it would be nice to label issue this as an enhancement, and the --removePrefix used should end in ormconfig.json.

Here is the code i used in the strategy:

let entityPrefix = getFromArgv('--removePrefix') || '';

function entityName(oldEntityName, entity) {
    let ep = entityPrefix;
    if (ep && ep.trim().length && oldEntityName.startsWith(ep)) {
        entity.sqlName = entity.sqlName.substr(ep.length);
        entity.columns = entity.columns.map(item => {
            if (item.hasOwnProperty('default') && item.default) {
                item.default = item.default.replace(/"'(.*)'"/gi, '"$1"')
            }
            return item;
        })
        return oldEntityName.substr(ep.length);
    }
    return oldEntityName;
}

$ typeorm-model-generator --namedStrategy=./CustomFile.js --removePrefix web_ ...connectionProps

This is not likely to be implemented - #329.
Custom naming strategy is a proper way to achieve the behavior you want.
